the weyl extension algebra of gl2 f p
Advances in Mathematics, 2013Co-Authors: Vanessa Miemietz, Will TurnerAbstract:Abstract We compute the Yoneda extension algebra of the collection of Weyl modules for G L 2 over an Algebraically Closed Field of characteristic p > 0 by developing a theory of generalised Koszul duality for certain 2-functors, one of which controls the rational representation theory of G L 2 over such a Field.

arXiv: Representation Theory, 2011Co-Authors: Vanessa Miemietz, Will TurnerAbstract:We compute the Yoneda extension algebra of the collection of Weyl modules for $GL_2$ over an Algebraically Closed Field of positive characteristic p by developing a theory of generalised Koszul duality for certain 2-functors, one of which controls the rational representation theory of $GL_2$ over such a Field.

graded involutions on block triangular matrix algebras
Linear Algebra and its Applications, 2020Co-Authors: Claudemir Fidelis, Dimas Jose Goncalves, Diogo Diniz, Felipe Yukihide YasumuraAbstract:Abstract In this paper we classify the ordinary and graded involutions on block-triangular matrix algebras over an Algebraically Closed Field of characteristic ≠2.
-
graded isomorphisms on upper block triangular matrix algebras
Linear Algebra and its Applications, 2018Co-Authors: Alex Ramos Borges, Claudemir Fidelis, Diogo DinizAbstract:Abstract We describe the graded isomorphisms of rings of endomorphisms of graded flags over graded division algebras. As a consequence we describe the isomorphism classes of upper block triangular matrix algebras (over an Algebraically Closed Field of characteristic zero) graded by a finite abelian group.

affine slice for the coadjoint action of a class of biparabolic subalgebras of a semisimple lie algebra
arXiv: Representation Theory, 2011Co-Authors: Patrice Tauvel, Rupert W T YuAbstract:In this article, we give a simple explicit construction of an affine slice for the coadjoint action of a certain class of biparabolic (also called seaweed) subalgebras of a semisimple Lie algebra over an Algebraically Closed Field of characteristic zero. In particular, this class includes all Borel subalgebras.
