Abstract

We prove that for a wide class of spaces $X$ the homology of the free loop space $H_*(X^{S^1} ; \mathbb{Q})$ has a very strong exponential growth. We call this convergence, controlled exponential growth, and we prove the good behavior of the controlled exponential growth with respect to fibrations.
