Saddle point and Morse index. The saddle point x of a potential function V(x) is a critical point at which the partial derivatives of a function V(x) are zero but is not an extremum. The Morse index of a critical point of a smooth function V(x) on a manifold is the negative inertia index of the Hessian matrix of the function V(x ...
WebJan 15, 2024 · As soon as a saddle point is found, people will pay attention to its Morse index. The instability is an important character to a saddle point. For nondegenerate saddle points, the Morse indices can be used to measure their instability and classify them.
