Mathematical physics lies at the intersection of mathematics and physics and is concerned with understanding the mathematical structures behind physical theories. The type of problems occupying mathematical physicists range from establishing rigorous mathematical foundations for physical theories, to exploring the structure and implications (both physical and purely mathematical) of these theories. An inclusive point of view would suggest that most areas of mathematical study are connected to mathematical physics and indeed the tools of analysis, algebra, geometry, probability and topology all are of use in the study of these problems.
