设M是紧化C流形,dimR M = M, h是莫尔斯函数,即所有临界点都是非简并的函数。标准莫尔斯不等式将贝蒂数bq = dimH q DR(M,R)和指数q的数字sq = #临界点联系起来,其中临界点的指数是Hessian形式(∂h/∂xi∂xj)的负特征值的数量。具体来说,以下“强莫尔斯不等式”成立:
Let M be a compact C manifold, dimR M = m, and h a Morse function, i.e. a function such that all critical points are non degenerate. The standard Morse inequalities relate the Betti numbers bq = dimH q DR(M,R) and the numbers sq = # critical points of index q , where the index of a critical point is the number of negative eigenvalues of the Hessian form (∂h/∂xi∂xj). Specifically, the following “strong Morse inequalities” hold :
