William Floyd (mathematician)

William J. Floyd is an American mathematician specializing in topology.

He is currently a professor at Virginia Polytechnic Institute and State University.

Floyd received a PhD in mathematics from Princeton University 1978 under the direction of William Thurston.

Floyd and Allen Hatcher classified all the incompressible surfaces in punctured-torus bundles over the circle.

[4][5] Floyd also wrote a number of joint papers with James W. Cannon and Walter R. Parry exploring a combinatorial approach to the Cannon conjecture[6][7][8] using finite subdivision rules.
