摘要：

In this paper, we study the gradient estimate for the positive solutions of the equation Delta u + au (log u)(p) + bu = f on an almost Ricci soliton (M-n, g, X, lambda). In a special case, when X = del h h for a smooth function h, we derive a gradient estimate for an almost gradient Ricci soliton.
