Special Issue Information

Dear Colleagues,

Algebra and number theories have always attracted the human mind, stimulated man’s curiosity, and have significantly contributed to forging the mathematical disciplines that pervade every aspect of modern life. Although it is difficult to foresee the future domains of application of aimless pure mathematical discoveries, today’s dominating fields are information theory and cryptography.

The prophetic words of Abraham Adrian Albert, stating that “abstract cryptography is identical with abstract mathematics”, could not be truer today in view of the reliance of modern society on cryptography for connectivity and intelligent systems. The prophecy may have included fascinating branches and problems in algebra and number theory; in particular, those of a computational and combinatorial nature such as the following:

  • Finite fields
  • Generation of sequences with random characteristics and the study of their complexity
  • The intractability of standard lattice problems, such as the shortest vector and the closest vector problems
  • Non-associative algebraic structures
  • The intractability of the general decoding problem for linear codes
  • Pairings, isogenies, and arithmetic of elliptic curves
  • Integer factoring, distribution of primes, and primality proving

Recently, applications involving many of the above branches and problems have been emerging for potential use in post-quantum cryptography. Although this trend is in line with today’s credo in applicable mathematics, the most relevant aspects of algebra and number theory are ultimately their beauty and the satisfaction of the human spirit: Fermat’s Last Theorem is likely the most eloquent example of that.

Magnifiers in Some Generalization of the Full Transformation Semigroups
Mathematics 2020, 8(4), 473; https://doi.org/10.3390/math8040473 - 30 Mar 2020
An element a of a semigroup S is called a left [right] magnifier if there exists a proper subset M of S such that a M = S ( M a = S ) . Let T ( X ) denote the semigroup [...] Read more.
An element a of a semigroup S is called a left [right] magnifier if there exists a proper subset M of S such that a M = S ( M a = S ) . Let T ( X ) denote the semigroup of all transformations on a nonempty set X under the composition of functions, P = { X i i Λ } be a partition, and ρ be an equivalence relation on the set X. In this paper, we focus on the properties of magnifiers of the set T ρ ( X , P ) = { f T ( X ) ( x , y ) ρ , ( x f , y f ) ρ and X i f X i for all i Λ } , which is a subsemigroup of T ( X ) , and provide the necessary and sufficient conditions for elements in T ρ ( X , P ) to be left or right magnifiers.
