Strong Morse Inequalities

Definition

Strong Morse inequalities are mathematical expressions that provide a relationship between the critical points of a smooth function and the topology of the underlying manifold. They enhance the classical Morse inequalities by accounting for additional structural information, making them useful for understanding the behavior of functions defined on manifolds and their implications for the manifold's topology.
