# Penn State's John Roe to Give October 26 Math Colloquium

**Oct. 24, 2012**

Professor John Roe, from Penn State University, will give a colloquium lecture "*The Naked Homeomorphism: The Mysterious Topology of Ordinary Space*" on Friday, October 26 at 3:30 pm in SR 207.

**John Roe**

Dr. Roe earned his bachelor's and master's degrees from Cambridge University and his doctorate, in 1985, from Oxford University. His Ph.D. supervisor was Sir Michael Atiyah. John has been a faculty member in the Departmnet of Mathematics at Penn State since 1998 and recently finished a (long) stint as Chair of the department.

A reception for Dr. Roe will be held at 3:00 pm in SR 318. All students and faculty are welcome!

**Title**: The Naked Homeomorphism: The Mysterious Topology of Ordinary Space

**Abstract**

The title comes from a famous survey paper by Larry Siebenmann, "Topological Manifolds". The theme is two-fold...(a) mysterious phenomena (e.g. space-filling curves, the Alexander horned sphere) which manifest themselves when we move from talking about __differentiable__ functions to just about __continuous__ ones, and (b) the fact that these "*monsters*" actually, in the end, make the topological "*zoo*" a place of greater order and beauty than the differentiable one.
