Caltech mathematicians have pushed the frontiers of mathematical physics, analysis, number theory, combinatorics, and group theory. They have mentored generations of students and written texts that are foundational to the field. With the renewal of the former Sloan Lab, Caltech’s Department of Mathematics will have a home commensurate with its achievements and ambitions. By naming a space in Ronald and Maxine Linde Hall of Mathematics, you can help realize the department’s potential to create a world-class teaching and research center.
