In this article, for a prime ideal

ρ

of an arbitrary ring ℜ, we study the commutativity of the quotient ring

ℜ / ρ

, whenever ℜ admits a generalized reverse derivation

ϑ

associated with a reverse derivation ∂ that satisfies certain identities in

ρ

. Additionally, we show that, for some cases, the range of the generalized reverse derivation

ϑ

lies in the prime ideal

ρ

. Moreover, we explore several consequences and special cases. Throughout, we provide examples to demonstrate that various restrictions in the assumptions of our results are essential. Full article

Let S be a 2-torsion free semiprime ring and U be a noncentral square-closed Lie ideal of

S .

An additive mapping ℏ on S is defined as a homoderivation if

ℏ (a b) = ℏ (a) ℏ (b) + ℏ (a) b + a ℏ (a)

for all

a, b \in S .

In the present paper, we shall prove that ℏ is a commuting map on U if any one of the following holds: (i)

ℏ ({\tilde{a}}_{1} {\tilde{a}}_{2}) + {\tilde{a}}_{1} {\tilde{a}}_{2} \in Z,

(ii)

ℏ ({\tilde{a}}_{1} {\tilde{a}}_{2}) - {\tilde{a}}_{1} {\tilde{a}}_{2} \in Z,

(iii)

ℏ ({\tilde{a}}_{1} \circ {\tilde{a}}_{2}) = 0,

(iv)

ℏ ({\tilde{a}}_{1} \circ {\tilde{a}}_{2}) = [{\tilde{a}}_{1}, {\tilde{a}}_{2}],

(v)

ℏ ([{\tilde{a}}_{1}, {\tilde{a}}_{2}]) = 0,

(vi)

ℏ ([{\tilde{a}}_{1}, {\tilde{a}}_{2}]) =

({\tilde{a}}_{1} \circ {\tilde{a}}_{2}),

(vii)

{\tilde{a}}_{1} ℏ ({\tilde{a}}_{2}) \pm {\tilde{a}}_{1} {\tilde{a}}_{2} \in Z,

(viii)

{\tilde{a}}_{1} ℏ ({\tilde{a}}_{2}) \pm {\tilde{a}}_{2} {\tilde{a}}_{1} = 0,

(ix)

{\tilde{a}}_{1} ℏ ({\tilde{a}}_{2}) \pm {\tilde{a}}_{1} \circ {\tilde{a}}_{2} = 0,

(x)

[ℏ ({\tilde{a}}_{1}), {\tilde{a}}_{2}] \pm {\tilde{a}}_{1} {\tilde{a}}_{2} = 0,

(xi)

[ℏ ({\tilde{a}}_{1}), {\tilde{a}}_{2}] \pm {\tilde{a}}_{2} {\tilde{a}}_{1} = 0,

for all

{\tilde{a}}_{1}, {\tilde{a}}_{2} \in U,

where ℏ is a homoderivation on

S .

In this paper, we introduce a new class of rings, called i-commutative rings, by extending the concept of commutative-like rings using idempotent elements. In particular, we study rings with the property that, whenever

a b + c d

is a nontrivial idempotent, then

b a + d c

is idempotent. We explore the basic properties of these rings and their relations with other rings. Moreover, we provide some examples using matrices and describe the structure of the idempotent elements in these rings. Full article

To facilitate the parallel development of the structures and properties of two-parameter quantum groups with those of one-parameter quantum groups, this paper primarily elucidates the interrelations and distinctions between the derivation algebras of these two types of quantum groups. Additionally, we also proposed a method for deriving the derivation algebra of one-parameter quantum groups from known two-parameter quantum group derivations, and vice versa. Full article

The goal of the present paper is to provide a cohomology theory and crossed modules of modified Rota–Baxter pre-Lie algebras. We introduce the notion of a modified Rota–Baxter pre-Lie algebra and its bimodule. We define a cohomology of modified Rota–Baxter pre-Lie algebras with coefficients in a suitable bimodule. Furthermore, we study the infinitesimal deformations and abelian extensions of modified Rota–Baxter pre-Lie algebras and relate them with the second cohomology groups. Finally, we investigate skeletal and strict modified Rota–Baxter pre-Lie 2-algebras. We show that skeletal modified Rota–Baxter pre-Lie 2-algebras can be classified into the third cohomology group, and strict modified Rota–Baxter pre-Lie 2-algebras are equivalent to the crossed modules of modified Rota–Baxter pre-Lie algebras.

⋀_{s t, t}^{* c o p}

D (⋀_{s t, t}^{* c o p})

has two ribbon elements, and if both s and t are odd, then

D (⋀_{s t, t}^{* c o p})
