Asprey Lecture

The Asprey Lecture Series is an annual series of lectures featuring the country’s most prominent mathematicians. The lecture series is in honor of Winifred Asprey, a Vassar graduate who taught mathematics and computer science at Vassar for 38 years before her retirement in 1982.  Professor Asprey was one of the most admired members of the Vassar faculty and was nationally recognized as a spokesperson for mathematics and computer science.  She founded Vassar’s Computer Center in the mid-60’s—one of the first such at a liberal arts college.   She continued to live in the Poughkeepsie area until her death in 2007.

2023-24 Asprey Lectures

Professor Laura DeMarco from Harvard University will deliver the 2023-24 Asprey Lectures February 8-9, 2024.

Abstract: The field of dynamical systems has a long and fascinating history:  it originated with the study of planetary motion and has become a central part of mathematics today, with many connections to algebra, geometry, and analysis.  In this talk, I will present some of its historical development, with emphasis on the subtle question of linearization and how that leads to deep and difficult problems that remain unsolved today.


Abstract: One of the most famous–and still not fully understood–objects in mathematics is the Mandelbrot set.  By definition, it is the set of complex numbers c for which the recursive sequence {c, c^2+c, (c^2+c)^2+c, …}, defined by x_1 = c and x_{n+1} = (x_n)^2+c, is bounded.  But this set turns out to be rich and complicated and related to many different areas of mathematics.  I will present an overview of what’s known and what’s not known about the Mandelbrot set, and I’ll describe recent work that (perhaps surprisingly) employs tools from arithmetic geometry to study these systems.  The new work is a collaboration with Myrto Mavraki.
