The stable cohomology of self-equivalences of connected sums of products of spheres

Abstract

We identify the cohomology of the stable classifying space of homotopy automorphisms (relative to an embedded disk) of connected sums of $S^k\times S^l$, where $3\le k<l\le 2k-2$. The result is expressed in terms of Lie graph complex homology.
