### SMS lecture series 2022: What is a generalized function?

### Audience

General (Suitable for students at Secondary Level and above with some familiarity with calculus)

### Description

This lecture series will feature eminent local mathematicians or mathematics educators to share with the public some of their interests and ideas.

### Speaker

Zhu Chengbo is Provost’s Chair Professor of Mathematics at the National University of Singapore. He received his BSc from Zhejiang University in 1984, and his PhD from Yale University in 1990, and joined NUS the following year. His research interests are in representation theory and invariant theory.

Professor Zhu served as the President of the Singapore Mathematical Society from 2009 to 2012 and is a Fellow of the Singapore National Academy of Science. He is an invited speaker of the 2022 International Congress of Mathematicians to be held in St. Petersburg, Russia.

### Abstract

As the name suggests, generalized functions are mathematical objects generalizing the notion of functions. The most famous example of a generalized function is the Dirac delta “function”, which is actually not a function in the usual sense, yet boldly used by Dirac and others as if it were, to great success. In this lecture, the speaker will explain the theory of generalized functions by L. Schwartz in its simplest form, and discuss the manifold uses and benefits of this theory.
