It was claimed that the new science, catastrophe theory, was much more valuable to mankind than mathematical analysis: while Newtonian theory only considers smooth, continuous processes, cat

Cutting and Packaging Optimizationies and so on). Astrophysicists nowadays think that in the early stages of the development of the universe there was no such inhomogeneity. How did it come about? Ya. B. Zel’dovich in 1970 proposed an explanation of the formation of clusters of dustlike material that is mathematically equivalent to

János Abonyi,László Nagy,Tamás Rupperttion, control theory and decision theory. For instance, suppose we have to find . such that the value of a function .(.) is maximal. Under a smooth change of the function the optimal solution changes with a jump from one of the two competing maxima . to the other ..

https://doi.org/10.1007/978-3-031-47444-6 the obstacle consists of straight-line segments and segments of geodesics (curves of minimal length) on the surface of the obstacle. The geometry of the shortest paths is greatly affected by the various bendings of the obstacle surface.

https://doi.org/10.1007/978-3-031-47686-0 the various singularities in optimization and variational calculus problems) become understandable only within the framework of the geometry of symplectic and contact manifolds, which is refreshingly unlike the usual geometries of Euclid, Lobachevskij and Riemann.
