In this Note, we give a proof of the famous theorem of M. Morse dealing with the cancellation of a pair of non-degenerate critical points of a smooth function. Our proof consists of a reduction to the one-dimensional case where the question becomes easy to answer.
Dans cette Note, nous présentons une preuve du célèbre théorème de M. Morse concernant lʼélimination dʼune paire de points critiques non dégénérés pour une fonction sur une variété différentiable. Notre preuve consiste à réduire la question au cas facile dʼune fonction dʼune variable.
