Wiener’s Lemma and Applications
Qiyu Sun
University of Central Florida
Professor of Mathematics
“The classical Wiener’s lemma states that if f(x) is a function with an absolutely convergent Fourier series, which nowhere vanishes for real arguments, 1/f(x) has an absolutely convergent Fourier series. In this talk, I will discuss various aspects of Wiener’s lemma from reciprocal of periodic functions to inverse of matrices and to inverse functions, and their applications to spectral invariance of integral operators and signal processing on spatially distributed networks.”
Light refreshments will be served @ 1:30PM in EMS E424A.
