Rank varieties and projectivity for a class of local algebras
We consider algebras K[X1,... , Xm]/(X i2), where K is an algebraically closed fields. To any finite dimensional module for this algebra we associate a rank variety. When char(K) = 2 we recover Carlson's rank variety. The main result states that a module is projective if and only if its rank va...
