THE DEGENERATIONS FOR MODULES AND DUAL MODULES
Let L be a finite-dimensional algebra over algebraically closed field and be an algebra opposite to L. Denote by and the category of all d-dimensional right modules over -algebra L and d-dimensional left modules over -algebra In this paper, we show that a module M in degenerates to another module N in if and only if dual module in degenerates to dual module in
degeneration, dual module.
