摘要：

Let p,phi be the weighted p-Laplacian defined on a smooth metric measure space. We study the evolution and monotonicity formulas for the first eigenvalue, 1=(p,phi), of p,phi under the Ricci-harmonic flow. We derive some monotonic quantities involving the first eigenvalue, and as a consequence, this shows that 1 is monotonically nondecreasing and almost everywhere differentiable along the flow existence.
