In this paper,we derive the evolution equation for the first eigenvalue of Laplace operator along Yamabe flow.We prove that on the smooth homogeneous manifold(Mn,g0),if λ(t) denotes the first eigenvalue of Laplace operator,then under normalized Yamabe flow,we have λ=d,and we can also get under the unnormalized Yamabe flow,λ(t)=dect,where c is the scalar curvature of smooth homogeneous manifold and d is a constant.Moreover,as applications,we construct some monotonic quantities under this flow.
