摘要
Let f be a self-map of a smooth compact connected and simply-connected manifold of dimension m >= 3, r a fixed natural number. In this paper we define a topological invariant D-r(m)[f] which is the best lower bound for the number of r-periodic points for all C-1 maps homotopic to f. In case m = 3 we give the formula for D-r(3)[f] and calculate it for self-maps of S-2 x I.
