Katsura Laboratory - Research on the Fascinating and Profound Mathematics of "Infinity" and Operator Algebra Theory

In the world of mathematics, many fields have histories spanning hundreds or even thousands of years. In comparison, operator algebra theory, the subject of research at the Katsura Laboratory, has a relatively short history. It was created in 1929 by John von Neumann, one of the most important figures in the history of 20th-century science, for the purpose of mathematically describing quantum mechanics.
