摘要
We compute the monoid of essential self-maps of S-n x S-n fixing the diagonal. More generally, we consider products S x S, where S is a suspension. Essential self-maps of S x S demonstrate the interplay between the pinching action for a mapping cone and the fundamental action on homotopy classes under a space. We compute examples with non-trivial fundamental actions. Crown Copyright (C) 2011 Published by Elsevier B.V. All rights reserved.
