Logic Seminar
Speaker: Laurel Miller-Sims (Smith College)
Time: Monday, November 30, 2009 at 5:05 pm
Place: Exley Science Center 618 (Wesleyan)
Abstract: Given a valued field (K,v), we say that a rational function f(x)
in K(x) is integral or infinitesimal definite on the definable set S
if v(f(b)) ≥ 0 or v(f(b))>0, respectively, for each b in S.
I will give algebraic characterizations of integral definite and
infinitesimal definite rational functions in various model-complete
theories of valued fields, analogous to the Positivstellensatz and
Negativstellensatz for real closed fields.

Abstract: In the beginning of the 19th century, Joseph Fourier developed an infinite series of sine and cosine functions to describe heat flow in a long, thin rectangular plate. However, his assertions ran contrary to the prevailing understanding of functions and infinite series. It took some time for the mathematical world to accept his findings, but today we know Fourier series are extremely important and have led to a whole branch of mathematics called Fourier Analysis. In this talk, I will introduce Fourier series and the Fourier transform and show some applications.
