In General > s.a. field theory; gauge theory.
* Goal: Use a well-defined framework, a precise language, and the standards of rigor of modern mathematics to
(1) Determine consequences of physical theories, by proving theorems about physically motivated concepts;
(2) Derive properties and numbers of physical interest for model systems through calculation.
Areas: see differential
equations, integral equations; operator
theory; group theory; differential geometry;
and, more recently, topology and algebraic
topology (including homotopy and homology).
Specific topics: see Banach Space; chern-simons theory; distributions; hilbert space; Response Functions; Special Functions.

Relationship between Mathematics and Physics
> s.a. Models; physics
[laws and ultimate theories]; proofs.
* Idea: It is a fact that we need math to investigate physical laws and to express them, since the laws are only understandable mathematically; In this view, one can see mathematics as a language invented by humans, or mathematicians, to model nature; But this is a partial view, the relationship is deeper and many believe that mathematics is nature.
* History: There was a close symbiosis through all of the XVIII century; They separated in the XIX century because of developments in pure math (number theory ...; Gauss ...) and new math-independent physics (Faraday ... J W von Goethe – see Ritter, Oersted – with his romantic natural philosophy), but in the XX century physics motivated many developments in mathematics, such as linear operator theory on Hilbert spaces, rigged Hilbert spaces, distributions, and unitary group representations.
* Quote: C N Yang: "What surprised me is not that gauge field is the connection of fiber bundles, but more so that mathematicians can create it without touching the world of physics. I was shocked and puzzled, because you mathematicians can create these ideas from nothing"; Reply by S S Chern: "No, no, these ideas are not just imagination, they are natural and real".]
* Areas developed together: Calculus, differential equations, variational theory, differential geometry.
* Areas of physics that have contributed to mathematics: Theory of brownian motion (analysis, probability); Gauge theories and instantons (differential geometry).
* Differences: Essentially, mathematics has no external constraints on what is interesting or relevant; Theoretical physics uses units/dimensions, and its results are subject to verification by experiment.
* Conjectures / rigor: Examples are Kepler's conjecture on close packing of spheres in \(\mathbb R\)3; Path integrals.
