Ela Celikbas, Jai Laxmi, Witold Kraśkiewicz +1
In this paper we define an interesting family of perfect ideals of codimension three, with five generators, of Cohen-Macaulay type two with trivial multiplication on the Tor algebr…

Generic decompositions and semi-invariants for string algebras
Witold Kraśkiewicz, Jerzy Weyman
We investigate the rings of semi-invariants for tame string algebras A(n) of non-polynomial growth. We are interested in dimension vectors of band modules. We use geometric techniq…
