Hybrid Nil Radical of a Ring

: The nature of universe problems is ambiguous due to the presence of asymmetric data in almost all disciplines, including engineering, mathematics, medical sciences, physics, computer science, operations research, artiﬁcial intelligence, and management sciences, and they involve various types of uncertainties when dealing with them on various occasions. To deal with the challenges of uncertainty and asymmetric information, different theories have been developed, including probability, fuzzy sets, rough sets, soft ideals, etc. The strategies of hybrid ideals, hybrid nil radicals, hybrid semiprime ideals, and hybrid products of rings are introduced in this paper and hybrid structures are used to examine the structural properties of rings.


Introduction
In [1], Zadeh developed and investigated fuzzy set theory and its features in relation to set theory, which gives a suitable structure for generalising fundamental algebraic ideas, including set theory, group theory, ring theory, etc. In group theory, Rosenfeld [2] explored the perception of a fuzzy set. Kuroki [3][4][5] has proposed fuzzy ideal structures and biideals in the theory of semigroups. Liu [6] explored the fuzzy ideal of a ring and obtained significant results. Mukherjee et al. [7] defined and discussed the fuzzy prime ideal notion of a ring. Later, fuzzy prime ideals were further discussed by Swamy et al. [8]. Malik [9] studied the fuzzy maximal and radical of a ring. Kumbhojkar et al. [10] studied fuzzy nil radicals of a ring. A fuzzy nil radical in different algebraic structures was explored by several researchers [11][12][13][14]. The fuzzy subnear-ring theory concept was presented by Abou-Zaid [15]. Since then, many mathematicians have pursued their research in fuzzy algebraic structures in different directions and obtained significant results in semigroups, groups, rings, etc.
Molodtsov [16] introduced and examined the soft set theory idea to deal with uncertainty concepts. Later on, different researchers looked at these ideas. The hybrid structure idea, which is parallel to fuzzy set theory and soft set theory, was initiated by Jun et al. [17] and obtained various results, and then applied to the theory of BCI/BCKalgebras. Anis et al., in [18], presented hybrid structures in semigroups, including hybrid subsemigroups, and hybrid ideals, and analysed their significant properties.
Elavarasan et al. [19], investigated the concept of hybrid ideals and hybrid bi-ideals in semigroups and established equivalent conditions in terms of hybrid ideals and hybrid bi-ideals for a semigroup to be regular and intra-regular. They also used hybrid ideals and hybrid bi-ideals to characterise the left and right simple semigroups, as well as the completely regular semigroups. In [20], Porselvi et al. defined hybrid interior ideals and hybrid characteristic interior ideals of a semigroup and found some equivalent conditions for a hybrid structure to be a hybrid interior ideal of a semigroup. For a regular semigroup and an intra-regular semigroup, hybrid interior ideals and hybrid ideals are also shown to be the same.
In [21], Porselvi et al. introduced the concepts of hybrid interior ideals and hybrid simple in an ordered semigroup, discussed the characteristic hybrid structures using ideals and interior ideals, and defined the ordered semigroup in terms of various hybrid ideal structures. The equivalent condition for an ordered semigroup was also established to be simple. In [22], Porselvi et al. presented the ideas of hybrid AG-groupoid as well as equivalent claims for a semigroup to be regular, and explored several properties of hybrid ideal structures.
In [23], Elavarasan et al. hooked up the idea of hybrid ideals in a near-ring, established various properties, and discussed hybrid structure images using homomorphism. Muhiuddin et al. in [24] proposed and investigated a hybrid subsemimodule over semirings, investigated the representations of hybrid subsemimodules and hybrid ideals using hybrid products, and obtained some intriguing results on t-pure hybrid ideals in subsemimodules over semirings.
In a ternary semiring, Muhiuddin et al. [25] introduced hybrid ideals and k-hybrid ideals, proved various properties of k-hybrid ideals, and gave characterisations of hybrid intersections with respect to these k-hybrid ideals. There were also results based on the homomorphic hybrid preimage of a k-hybrid ideal. More concepts related to this study have been studied in [26][27][28][29][30][31][32][33][34].
The study of symmetry is one of the most important and beautiful themes uniting various areas of contemporary arithmetic. Rings are useful structures in pure mathematics for learning a geometrical object's symmetries. The most important functions in ring theory are those that preserve the ring operation, which are referred to as homomorphism. Showing a link from ring theory to real life is a simple way to see a possible connection between homomorphism and reality.
In this expository article, we discuss hybrid structures in ring theory, namely, hybrid ideals, hybrid semiprime ideals, hybrid nil radicals, hybrid products, and characteristic functions in rings, and present some results regarding these concepts. We also prove that the hybrid intersection of a hybrid radical will coincide with the hybrid radical of a hybrid intersection, the hybrid image of a hybrid radical will coincide with the hybrid radical of a hybrid image under certain conditions, and the hybrid preimage of a hybrid radical will coincide with the hybrid radical of a hybrid preimage. Further, we obtain an equivalent assertion for the hybrid semiprime ideal in the ring.

Definitions and Results
We will present the glossary of definitions that we will use in this sequel.

Definition 1.
A set R( = φ) together with two binary operations '+' and '.' is said to be a ring if it fulfils the following assertions: Throughout this paper, unless stated otherwise, R denotes a ring and P(X ), the power set of a set X .

Definition 2.
Let I be the unit interval and U be an initial universal set. Consider a mapping j µ := (j, µ) : R → P(U ) × I, x 1 → (j(x 1 ), µ(x 1 )), wherej : R → P(U ) and µ : R → I. Then,j µ is described as a hybrid structure in R over U .
Let all the hybrid structures collected in R over U be described by H (R). An order in H (R) is outlined as follows: For everyj µ ,l γ ∈ H (R),j µ l γ if and only ifj(w) ⊆l(w) and µ(w) ≥ γ(w) for all w ∈ R. For any x 1 , . Additionally,j µ l γ andl γ j µ if and only ifj µ =l γ . It is noted that (H (R), ) is a poset. Definition 3. Suppose (G , .) is a group. A hybrid structureĩ Ω ∈ H (R) is a hybrid subgroup in G if it fulfils the following assertions: ∀ a 1 , a 2 ∈ G , .

Definition 4.
Letĩ Ω ∈ H (R). Then, ∀ k 1 , w 2 ∈ R, i Ω is a hybrid left ideal in R if it fulfils assertions (i) and (ii),ĩ Ω is a hybrid right ideal in R if it fulfils assertions (i) and (iii), andĩ Ω is a hybrid ideal if it fulfils assertions (i), (ii), and (iii).

Definition 7 ([11]
). Let R be a commutative ring. An ideal K ⊆ R is termed as semiprime if, whenever d n ∈ K for some positive integer n and d ∈ R, then d ∈ K.
Theorem 1 ([11]). Suppose R is commutative. Then, every ideal of R is semiprime if and only if R is regular.

Definition 9.
Consider a map Ψ : S → T , where S and T are sets. For any hybrid structurẽ For anyĩ Ω ∈ H (S ) over U , under the mapping Ψ, the hybrid image ofĩ Ω is considered as a hybrid structure Ψ(ĩ Ω ) : This is called characteristic hybrid structure of A.

Hybrid Structures in Rings
We define the hybrid radical notion in a ring and explore its properties. We also show that for any two hybrid ideals, the hybrid radical of the hybrid intersection is equivalent to the hybrid intersection of the hybrid radical, and the hybrid radical of the hybrid sum is equivalent to the hybrid sum of the hybrid radical.

Definition 11.
Supposeĩ Ω ∈ H (R) is a hybrid ideal in R. Then, the hybrid nil radical ofĩ Ω is the hybrid structure in R over U , represented by ĩ Ω := (
Theorem 2. Let R be a commutative ring andĩ Ω ∈ H (R) a hybrid ideal in R. Then, ĩ Ω is a hybrid ideal in R.

Proof.
Let v, u ∈ R. Then, for positive integers r, s, we have Since R is commutative, all the terms in (v + u) r+s contain either v r or u s as a factor. Therefore, (v + u) r+s = xv r + yu s for some x, y ∈ R. Now, √ Ω(u)} ≥ √ Ω(vu) and hence ĩ Ω is a hybrid ideal in R.

Definition 12.
Letĩ Ω ,j γ ∈ H (R) be hybrid ideals in R. Then, the hybrid intrinsic product i Ω * jγ is the hybrid structure in R stated as below: For x ∈ R, define It is evident that if R is commutative, thenĩ Ω * jγ is commutative.

Definition 14.
Consider the function Ψ : and Ω(u) = Ω(v) for any u, v ∈ S . Theorem 6. Consider the ring homomorphism Ψ : R → S . Ifĩ Ω andj γ are hybrid ideals in R and S , respectively, then the following assertions hold: Proof.
Proof. Let c, v ∈ R andĩ Ω be a hybrid left ideal in S . Then, Additionally, Theorem 8. Consider Ψ : R → S as onto ring homomorphism. Ifj γ ∈ H (R) is a Ψ-invariant hybrid left (resp, right) ideal in R, then Ψ(j γ ) is a hybrid left (resp, right) ideal in S .

Hybrid Semiprime Ideals in Commutative Rings
We discuss some properties of hybrid semiprime ideals of a ring and we characterise rings in terms of hybrid semiprime ideals. We also obtain an equivalent assertion for the hybrid semiprime ideal. Throughout this section, unless otherwise stated, R denotes a commutative ring.

Definition 15.
A hybrid idealĩ Ω ∈ H (R) in R is hybrid semiprime whenever ĩ Ω =ĩ Ω . Example 2. Let K be a semiprime ideal of R. Letĩ Ω in H (R) over U = [0, 1] be given bỹ 1] i f k / ∈ K and a mapping Ω : R → I be constant. Then,ĩ Ω is a hybrid semiprime ideal in R.
Theorem 9. For any Q ∈ P(R) andĩ Ω ∈ H (R), we have that Q is a semiprime ideal if and only if χ Q (ĩ Ω ) is a hybrid semiprime ideal.
Proof. (i) ⇒ (ii) Let n 1 be any positive integer and u ∈ R. Then, and , i Ω .

Theorem 12.
Letĩ Ω ∈ H (R). Then, the equivalent assertions are as follows: (i) Every hybrid idealĩ Ω in R is a hybrid semiprime ideal, (ii) R is regular.
Proof. (i) ⇒ (ii) Suppose X is an ideal of R. Then, χ X (ĩ Ω ) is a hybrid semiprime ideal in R. By Theorem 9, X is semiprime. Thus, R is regular by Theorem 1.

Conclusions
We developed an understanding of how hybrid nil radicals, hybrid ideals, hybrid products, and hybrid semiprime ideals operate in rings and discussed several of their properties. We have shown that for any hybrid ideal, the hybrid radical of the hybrid intersection is equivalent to the hybrid intersection of the hybrid radical. We also obtained an equivalent assertion for the hybrid radical of the hybrid intrinsic product, as well as a hybrid semiprime ideal. A future research project explores hybrid primes and hybrid quasi-primes in algebraic structures and establishes their structural properties.
