Marston Morse

Marston Morse refers to a mathematical concept related to Morse theory, which was developed by the American mathematician Marston Morse in the early 20th century. Morse theory is a branch of differential topology that studies the topology of manifolds using smooth real-valued functions defined on them, known as Morse functions. A Morse function is a smooth function where its critical points (points where the gradient is zero) have distinct non-degenerate critical values.
