Robert S. Strichartz, professor of mathematics at Cornell University, whose research interests range from harmonic analysis, partial differential equations and integral geometry, will deliver a pair of free public talks as part of the Carl J. Rees Distinguished Lecturer Series.

Strichartz will speak on “Sampling Theory for Functions with Fractal Spectrum” at 3:30 p.m., Thursday, Feb. 28, in 231 MBNA America Hall.

At 3:30 p.m., Friday, March 1, in 104 Gore Hall, he will discuss “Differential Equations with Fractals.”

Strichartz’s early work using methods of harmonic analysis to obtain fundamental estimates for linear wave equations has played an important role in recent developments in the theory of nonlinear wave equations.

His work on fractals began with the study of self-similar measures and their Fourier transforms. Recently, through an undergraduate summer research program which he directs at Cornell, Strichartz has been concentrating his efforts on a theory of differential equations on fractals created by Jun Kigami.

The author of “A Guide to Distribution Theory and Fourier Transform” and “The Way of Analysis,” Strichartz is the author of numerous papers and has helped students in the creation of various web sites. He received his doctorate from Princeton University in 1966.

Sponsored by the Department of Mathematical Sciences, the Carl J. Rees Distinguished Lecturer Series honors the distinguished contributions by Prof. Rees at UD from 1920-1947, a career which included service as University provost, dean of the College of Graduate Studies and chairperson of the Department of Mathematics.
