A construction of Gorenstein-projective modules
ZW Li, P Zhang - Journal of Algebra, 2010 - Elsevier
We determine all the Gorenstein-projective modules over the T2-extension of a Gorenstein
algebra, and over (AM0B), where A and B are self-injective algebras, and M is an AB …

Representation dimension of extensions of hereditary algebras
M Saorín - Journal of Pure and Applied Algebra, 2010 - Elsevier
We show that if H is a hereditary finite dimensional algebra, M is a finitely generated H-
module and B is a semisimple subalgebra of EndH (M) op, then the representation …

Produto fibrado orientado de álgebras e dimensão de representação
H Wagner - 2012 - teses.usp.br
Dados dois epimorfismos de álgebras $ f\\colon A\\to B $ e $ g\\colon C\\to B $, o produto
fibrado é a subálgebra $ R $ de $ A\\times C $ definida por $\\{(a, c)\\in A\\times C\\mid f (a) …
