On the unification of heterotic strings, M theory and E(∞) theory

The work points out the existence of various theoretical and numerical evidences for a possibly deep connection between the high but finite dimensionality of heterotic strings and M theory on the one side and the infinite-dimensional E-(infinity) Cantorian theory on the other. It is conjectured that various modern strings theories are presumably the best possible description of actual quantum space-time within a finite-dimensional theory. It is further conjectured that the E-(infinity) theory provides the mathematical framework for a possible stringent proof of this conjecture. (C) 2000 Elsevier Science Ltd. All rights reserved.
