In this paper, we show the following main results. Let ( M n ,g(t)), t ∈ [0, T ), be a solution of the unnormalized H k − flow on a closed manifold, and λ 1, p ( t ) be the first eigenvalue of the p ‐Laplace operator. If there exists a nonnegative constant ε such thatH kh ij −H k + 1pg ij ≥ − ε g ijin M × [0, T ) andH k + 1 > pε in M × [0, T ),then λ 1, p ( t ) is increasing and the differentiable almost everywhere along the unnormalized H k − flow on [0, T ). At last, we discuss some useful monotonic quantities. Copyright © 2013 John Wiley & Sons, Ltd.
