On the Breen-Baez-Dolan stabilization hypothesis for Tamsamani's weak n-categories

Abstract

We show that if $2k\ge n$, then a k-connected weak n-category $A$ can be ``delooped'' to a k+1-connected weak n+1-category $Y$ with $Ho{m}_Y(y,y)\cong A$. This is the essential part of the ``stabilization hypothesis'' of Baez and Dolan q-alg/9503002, math/9802029.
