Modules of complexity one over exterior algebras.
Let R be the graded exterior algebra of some finite dimensional vector
space. A non projective R-module X has complexity one,
if there exists an upper bound for the dimensions of all projective modules
occurring in a minimal projective resolution of X.
I will present results from a joint project with Dan Zacharia about
R-modules of complexity one, especially on those which are
