Let G be a group, F a field, and A a finite-dimensional central simple algebra over F on which G acts by F-algebra automorphisms. We study the subalgebras and ideals of A which are preserved by the group action. We prove a structure theorem and two classification theorems for invariant subalgebras u

โฆ Synopsis
Let A be a finite-dimensional central simple algebra and let k be a subfield of ลฝ . its center Z A . We say that z , . . . , z generate A as a central simple algebra
we give a necessary and sufficient condition for A to be generated by m elements as a central simple algebra over k.

Let D be a central division algebra and A ร =GL m (D) the unit group of a central simple algebra over a p-adic field F. The purpose of this paper is to give types (in the sense of Bushnell and Kutzko) for all level zero Bernstein components of A ร and to establish that the Hecke algebras associated
Let H H kQ be the RingelแHall algebra of affine quiver Q. All indecomposable ลฝ . representations of Q, which can be generated inside H H kQ by ''smaller'' represen-ลฝ . tations of Q, are classified; systems of minimal homogeneous generators of H H kQ are explicitly written out.
