### Computer Science/Discrete Mathematics Seminar II

The Lens of Abelian Embeddings
10:30am|Simonyi Hall 101 and Remote Access

A predicate $P:\Sigma^k \to {0,1}$ is said to be linearly embeddable if the set of assignments satisfying it can be embedded in an Abelian group.

In this talk, we will present this notion and mention problems it relates to from various areas...

### Special Year Research Seminar

On the Maximum of a Twisted Divisor Function
Dimitris Koukoulopoulos
2:00pm|Simonyi 101 and Remote Access

Given $n\in\mathbb{N}$ and $\xi\in\mathbb{R}$, let $\tau(n;\xi)=\sum_{d|n}d^{i\xi}$. Hall and Tenenbaum asked in their book \textit{Divisors} what is the value of $\max_{\xi\in[1,2]} |\tau(n;\xi)|$ for a typical'' integer $n$. I will present work...

### Princeton Center for Heliophysics Seminar

Into the Fire: Plasma Physics of the Turbulent Solar Corona
Steve Cranmer
3:00pm|Virtual Meeting

The solar corona is the hot and ionized outer atmosphere of the Sun. It traces out the complex solar magnetic field and expands into interplanetary space as the supersonic solar wind. In 1958, Eugene Parker theorized that the presence of a million...

### Special Year Research Seminar

Recognizing Groups in Erdős Geometry and Model Theory
Artem Chernikov
3:30pm|Simonyi 101 and Remote Access

Erdős-style geometry is concerned with combinatorial questions about simple geometric objects, such as counting incidences between finite sets of points, lines, etc. These questions can be typically viewed as asking for the possible number of...
