Morse function (plural Morse functions)

  1. A real-valued function on a differentiable manifold such that, at each point in its domain where the function's differential is zero, the function's Hessian is nonsingular.

Usage notes[edit]

  • Some sources require also for each that the preimage of be compact, or that the preimage of contain at most one point with zero differential.
