In this paper,let A be a finite dimensional associative algebra over an algebraically closed field k,modA be the category of finite dimensional left A-module an
Let H be a semisimple weak Hopf algebra,A a left H-module algebra.We prove that the injective dimension of the regular A-module is equal to the one of A as the
An algebraic system X is constructed by using the known loop ~A1.Then a new isospectral problem is established by taking advantage of X,which is devoted to worki
In this paper,two concepts of relative compactness-the relative strong fuzzy compactness and the relative ultra-fuzzy compactness are defined in L-topological s
