**Frank Stringfellow Quinn, III** (born 1946) is an American mathematician and professor of mathematics at Virginia Polytechnic Institute and State University, specializing in geometric topology.

## Contents

## Contributions

He contributed to the mathematical field of 4-manifolds, including a proof of the 4-dimensional annulus theorem. In surgery theory, he made several important contributions: the invention of the assembly map, that enables a functorial description of surgery in the topological category, with his thesis advisor, William Browder, the development of an early surgery theory for stratified spaces, and perhaps most importantly, he pioneered the use of controlled methods in geometric topology and in algebra. Among his important applications of "control" are his aforementioned proof of the 4-dimensional annulus theorem, his development of a flexible category of stratified spaces, and, in combination with work of R.D. Edwards, a useful characterization of high-dimensional manifolds among homology manifolds.

In addition to his work in mathematical research, he has written articles on the nature and history of mathematics and on issues of mathematical education.

## Awards and honors

In 2012 he became a fellow of the American Mathematical Society.
