Abstract

It is shown that if a Markov map TT on a noncommutative probability space M\mathcal{M} has a spectral gap on L2(M)L_2(\mathcal{M}), then it also has one on Lp(M)L_p(\mathcal{M}) for 1<p<1<p<\infty. For fixed pp, the converse also holds if TT is factorizable. These results are also new for classical probability spaces.
