#### Uncertainty in Fourier Analysis

Abstract: The foundational idea behind the Heisenberg Uncertainty Principle is that it is not possible to localize both a function and its Fourier transform simultaneously. I will be discussing some applications of uncertainty in Fourier analysis and speaking about some generalizations which are useful, specifically in how uncertainty can be used in a proof of the Malgrange-Ehrenpreis theorem.

#### Dp-minimal expansions of $(\mathbb{Q},<,+)$ (continued)

###### Erik Walsberg (Illinois Math)

Abstract: I will use P. Simon's result to relate dp-minimal expansions of $(\mathbb{Q},<,+)$ to o-minimal expansions of $(\mathbb{R},<,+)$, I will also describe a nice application of the Pettis lemma to o-minimality.
