In https://news.ycombinator.com/item?id=40572593 https://news.ycombinator.com/item?id=40572593 Arnold, his tongue in cheek (and channelling his inner GJC), suggests a tripartite division of maths according to the industrial form which supports the pure researches: - Celestial Mechanics (support: the descendants of von Braun): dynamical systems, linear algebra, topology, variational calculus, symplectic geometry - Cryptography (support: CIA, SVR, etc.): number theory, algebraic geometry over finite fields, algebra, combinatorics, and computers. - Hydrodynamics (support: boomer builders): complex analysis, partial derivative eqn's, Lie groups/algebras, cohomology theory, HPC. Might there be one small village of pure mathematicians still holding out against the industrial support?
