We study dimension of stable sets and scrambled sets of a dynamical system with positive finite entropy. We show that there is a measure-theoretically " large " set containing points whose sets of " hyperbolic points " (i.e., points lying in the intersections of the closures of the stable and unstable sets) admit positive Bowen dimension entropies, which,(More)
This is a joint work with Victor Ginzburg [4] in which we study a class of associative algebras associated to finite groups acting on a vector space. These algebras are non-homogeneous N-Koszul algebra generalizations of sym-plectic reflection algebras. We realize the extension of the N-Koszul property to non-homogeneous algebras through a(More)
For self-orthogonal modules T , the quotient triangulated categories D b (A)/K b (addT) are studied, in particular, their relations with the stable categories of some Frobenius categories are investigated. New descriptions of the sin-gularity categories of Gorenstein algebras are obtained; and the derived categories of Gorenstein algebras are explicitly(More)
