Harmonic Analysis Seminar

3:30 pm Lockett 232

Alexander Burgin, Georgia Tech
Integer Cantor sets: Harmonic-analytic properties & arithmetic applications.

Integer Cantor sets, which consist of a set of integers in a fixed base and a fixed set of digits, have many interesting properties, including uniform distribution, metric pair correlation, and mean ergodic theorems. In particular, their Fourier transform factorizes. I’ll begin with a motivation from ergodic theory, and proceed to discuss some recent results of myself, Fragkos, Lacey, Mena, and Reguera. If time permits, I will discuss some arithmetic applications of these estimates.

Variational Stability of Alternating Projections

The alternate projection method is a classical approach to deal with the convex feasibility problem. We shall first show that given two nonempty closed convex sets $A$ and $B$, the consecutive projections $x_{n+1} = PB(PA(x_n))$, $n \ge 1$ produce a self-contacted sequence, providing in particular an alternative way to establish convergence in the finite dimensional case [2]. In infinite dimensions, a regularity condition is required to ensure convergence of the above sequence $\{x_n\}_{n\ge 1}$ [4]. In [3], it was established that a regularity condition from [1] also ensures the variational stability of the above method. In this talk, we shall complete this result and show that variational stability is actually equivalent to the aforementioned regularity assumption. REFERENCES: [1] H. Bauschke, J.
