چکیده
|
Let gk,n be the grassmann manifold of k-planes in r n+k . the lusternik-schnirelmann category and topological complexity are important invariants of topological spaces. in this note we calculate the lusternik-schnirelmann category and topological complexity of certain products of grassmannian manifolds by using cup and zero-cup length. also we will find the lower and upper bounds of the topological complexity of some grassmannian manifolds by the same method
