摘要
设(M,g)是n维黎曼流形,n≥3.考虑(M,g)上的Yamabe soliton:(R-ρ)g=1/2LXg,其中R是数量曲率,X∈X(M)是光滑向量场,是实常数.证明了:如果流形是紧致的,则数量曲率R是常数.
Let(M,g) be an n-dimensional Riemannian manifold, n≥3. The following Yamabe soliton on (M,g) is stud 1 c ied: (R-p)g=1/2xg, where R is the scalar euvature, X∈(M) denotes a smooth vector field on M and p is a real constant, It is shown that if the manifold is compact, the scalar R is a constant.
