Mathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...

, aims to bring together top researchers in the field. It has a small number of permanent professors, appointed for life, and invites about 200 visitors a year for varying terms averaging three months. It also has a small number of so-called long-term visitors. Research is not contracted or directed: it is left to each individual researcher to pursue their own goals. Permanent professors are only required to be in residence six months a year.

Design of the IHÉS is said to be influenced by Robert Oppenheimer, who was then the Director of the Institute for Advanced Study
