We intend to continue the research on non commutative rings and applications. The research group has been working in this direction for quitea long time and has already obtained expressive results that are frequently quoted in the literature. The subjects that will be the object of our research in the forth coming period are, among others: the structure of group algebras and its applicati…
The aim of the research project is to the study three invariants ofa T-ideal of a free algebra with an additional structure in characteristic zero: thegrowth of the polynomial identities, of the central polynomials identities and of the proper centralpolynomial identities (AU)
VISIT OF ANTONINO GIAMBRUNO04.03.2023 - 04.05.2023SUMMARYWe shall focus on problems regarding the study of the so-called fundamentalalgebras. These were introduced by Kemer and played a prominent role is in thetheory of varieties of algebras. In a previous joint work, these algebras were used asa tool for the computation of a common polynomial factor in the functions givingthe upper and l…
We intend to study the possible extensions of group codes to more generalones; specifically, to codes that can be realized as ideals of crossed products, a structure that extends the notion of group algebra. To do so, we expect tostudy the primitive idempotents of semisimple crossed products, determinetheir number and methods to exhibit such elements and also determine theparameters of th…

Let * be an involution of a group algebra KG induced by an involution of the group G. We define *-identities in groups analogous to *-identities in rings. In this research project we aim to relate the *-identities of the unit group of KG to the nilpotence of the Lie algebra of *-skew elements of KG.
A cyclic code, is a linear code such that if c = (c1, ..., cn) C then (cn, c1, ..., cn-1) C.If we denote by Cn the cyclic group of order n and by FqCn the group algebra of Cn over Fq, it is easy to see that every cyclic code can be accomplished as an ideal this algebra. This view has the advantage of allowingusing the group structure to determine the parameters of a code.Recently, A. Sh…
The study of generating sets for the group of units of group rings is a very active area nowadays. Particularly, in the case of integral group rings, the importance of this research can be compared to Dirichlet's Theorem, for algebraic integers.Unfortunately, there are not general results about generating sets of units for integral group rings. However the researchers have been studying …
