The matrix Jacobson graph of finite commutative rings

open access: yesElectronic Journal of Graph Theory and Applications, 2022
The notion of the matrix Jacobson graph was introduced in 2019. Let R be a commutative ring and J(R) be the Jacobson radical of ring R. The matrix Jacobson graph of ring R size m × n, denoted 𝔍(R)m × n, is defined as a graph where the vertex set is Rm ...

PROJECTIVE GROUP ALGEBRAS [PDF]

open access: yesInternational Journal of Modern Physics A, 1999
In this paper we apply a recently proposed algebraic theory of integration to projective group algebras. These structures have received some attention in connection with the compactification of the M theory on noncommutative tori. This turns out to be an interesting field of applications, since the space [Formula: see text] of the equivalence classes ...

Twisted group algebras I [PDF]

open access: yesCommunications in Mathematical Physics, 1969
A generalization of the group algebra of a locally compact group is studied, by expressing the group algebra of a central group extension as the direct sum of closed *-ideals each one of which is isomorphic to such a “twisted” group algebra. In particular, the representation theory of such algebras is associated with the theory of projective ...

Algebraic subgroups of the plane Cremona group over a perfect field [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We show that any infinite algebraic subgroup of the plane Cremona group over a perfect field is contained in a maximal algebraic subgroup of the plane Cremona group.

A second order algebraic knot concordance group [PDF]

open access: yes, 2011
We define an algebraic group comprising symmetric chain complexes which captures the first two stages of the Cochran-Orr-Teichner solvable filtration of the knot concordance group in a single invariant.

C*-Algebraic Quantum Groups Arising from Algebraic Quantum Groups [PDF]

open access: yesInternational Journal of Mathematics, 1997
We associate to an algebraic quantum group a C*-algebraic quantum group and show that this C*-algebraic quantum group essentially satisfies an upcoming definition of Masuda, Nakagami and Woronowicz.

Cohomology of simple modules for algebraic groups

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
In this paper, we consider questions related to the study of the cohomology of simple and simply connected algebraic groups with coefficients in simple modules. There are various calculating methods for them. One of the effective methods is to study the
