On gradings of matrix algebras and descent theory
The aim of this paper is to investigate group gradings of matrix algebras. Let k be a field and G be a group. A k-algebra A is called G-graded if A = ⊕g∈GAg, a direct sum of k-subspaces, such that AgAh ⊆ Agh for any g,h ∈ G. Several papers have been devoted to constructing and classifying group gradings on the matrix algebra Mm(k). One can view the algebra Mm(k) as a quotient of the path algebr...
متن کاملCounting Fine Gradings on Matrix Algebras and on Classical Simple Lie Algebras
Known classification results allow us to find the number of fine gradings on matrix algebras and on classical simple Lie algebras over an algebraically closed field (assuming that characteristic is not 2 in the Lie case). The computation is easy for matrix algebras and especially for simple Lie algebras of Series B, but involves counting orbits of certain finite groups in the case of Series A, ...
متن کاملGradings on Symmetric Composition Algebras
The group gradings on the symmetric composition algebras over arbitrary fields are classified. Applications of this result to gradings on the exceptional simple Lie algebras are considered too.
متن کاملFine Gradings on Simple Classical Lie Algebras
The fine abelian group gradings on the simple classical Lie algebras (including D4) over algebraically closed fields of characteristic 0 are determined up to equivalence. This is achieved by assigning certain invariant to such gradings that involve central graded division algebras and suitable sesquilinear forms on free modules over them.
متن کاملGeneralized Matrix Algebras and Their Applications
The relations between the radicals of path algebras and connectivity of directed graphs are given. The relations between radicals of generalized matrix rings and Γrings are given. All the coquasitriangular structures of group algebra kG are found when G is a finitely generated abelian group. 2000 Mathematics subject Classification: 16w30, 05Cxx.
