Super-decomposable pure-injective modules over some Jacobian algebras
Shantanu Sardar
Existence of superdecomposable pure-injective modules reflects complexity in the category of finite-dimensional representations over an algebra. Such an existence occurs when an al…

Krull-Gabriel dimension of Skew group algebras
Shantanu Sardar
For an algebraically closed field K, let G be a finite abelian group of K-linear automorphisms of a finite-dimensional algebra A and AG is the associated skew group algebra. The au…
