Synopsis

Let f: Mm→Nn be a map from a Riemannian m-manifold (Mm, d) into an n-manifold Nn. The major purpose of this paper is to give a lower bound for the number

by examining the behaviour of the cohomology homomorphisms induced by f. This idea will be used to generalise the classical Newman theorem and present a geometric background for a well-known non-embedding theorem in topology.
