WebAug 17, 2024 · The folding catastrophe model is adopted as the potential function of the Schr'odinger equation, from which a revised Schrödinger relativistic equation through the dimensionless analysis is derived out. Furthermore, the steady-state Klein-Gordon equation and Dirac relativistic equation are gradually obtained. These results reveal that the ... WebThe catastrophe set can be viewed as the curve which goes along the border of the fold on the catastrophe manifold. It is the set of degenerated critical points and is described mathematically as the set \( { \{(x,u,v) \vert \partial_x F = \partial^{2}_x F = 0\} } \) . kentisbeare weather
