Koszul rings are graded rings which have played an important role in algebraic topology, noncommutative algebraic geometry and in the theory of quantum groups.

The 43 research papers demonstrate the application of recent developments in the representation theory of artin algebras and related topics. Among the algebras

After the development of manifolds and algebraic varieties in the previous century, mathematicians and physicists have continued to advance concepts of space. T

This refereed collection of research papers and survey articles reflects the interplay of finite-dimensional algebras with other areas (algebraic geometry, homo
