### Program Theme

For mathematics, string theory has been a source of many significant inspirations, ranging from Seiberg-Witten theory in four-manifolds, to enumerative geometry and Gromov-Witten theory in algebraic geometry, to work on the Jones polynomial in knot theory, to recent progress in the geometric Langlands program and the development of derived algebraic geometry and n-category theory. In the other direction, mathematics has provided physicists with powerful tools, ranging from powerful differential geometric techniques for solving or analyzing key partial differential equations, to toric geometry, to K theory and derived categories in D-branes, to the analysis of Calabi-Yau manifolds and string compactifications, to the use of modular forms and other arithmetic techniques.

The thematic program is to bringing together mathematicians and physicists who work on ideas related to string theory. String theory, as well as quantum field theory, have contributed a series of profound ideas which gave rise to entirely new mathematical fields and revitalized older ones.

The thematic program aims to engage the large and rapidly growing number of mathematicians and physicists working at the string-theoretic interface between the two academic fields and to facilitate the flow of ideas with mathematical techniques and ideas contributing crucially to major advances in string theory.
