Abstract: | In this paper, we show the following main results. Let (Mn,g(t)), t ∈ 0,T), be a solution of the unnormalized Hk ? flow on a closed manifold, and λ1,p(t) be the first eigenvalue of the p‐Laplace operator. If there exists a nonnegative constant ε such that in M × 0,T) and in M × 0,T),then λ1,p(t) is increasing and the differentiable almost everywhere along the unnormalized Hk ? flow on 0,T). At last, we discuss some useful monotonic quantities. Copyright © 2013 John Wiley & Sons, Ltd. |
