题目: Endotrivial modules for restricted Lie algebras
摘要: Given a finite-dimensional restricted Lie algebra (g,[p]), we let U_0(g) denote the restricted enveloping algebra of g. A U_0(g)-module M is endotrivial if End_k(M) is isomorphic to k+(proj), the direct sum of a one dimensional trivial module and a projective module. We introduce new invariants for endotrivial modules of restricted Lie algebras, called Syzygy degree. To an endotrivial module M, we define the Syzygy degree function of M and show that the function is constant.
