Algebras Generated by Elements with Given Spectrum and Scalar Sum and Kleinian Singularities

Anton Mellit

Published 2004-06-07Version 1

For a certain class of (nonunital) subalgebras of deformed preprojective algebra of affine type we describe their centers as certain deformation of Kleinian singularity and find their PI-degree. These results can be applied to algebras generated by elements with given spectrum and scalar sum.
