Topological methods in zero-sum Ramsey theory

Autor: Frick, Florian, Duke, Jacob Lehmann, McNamara, Meenakshi, Park-Kaufmann, Hannah, Raanes, Steven, Simon, Steven, Thornburgh, Darrion, Wellner, Zoe

A cornerstone result of Erd\H os, Ginzburg, and Ziv (EGZ) states that any sequence of $2n-1$ elements in $\mathbb{Z}/n$ contains a zero-sum subsequence of length $n$. While algebraic techniques have predominated in deriving many deep generalizations

On the cardinality of minimal presentations of numerical semigroups

Autor: Elmacioglu, Ceyhun, Hilmer, Kieran, O'Neill, Christopher, Okandan, Melin, Park-Kaufmann, Hannah

In this paper, we consider the following question: "given the multiplicity $m$ and embedding dimension $e$ of a numerical semigroup $S$, what can be said about the cardinality $\eta$ of a minimal presentation of $S$?" We approach this question from a

Ensemble Kalman Filtering for Glacier Modeling

Autor: Corcoran, Emily, Knudsen, Logan, Mayo, Talea, Park-Kaufmann, Hannah, Robel, Alexander

Working with a two-stage ice sheet model, we explore how statistical data assimilation methods can be used to improve predictions of glacier melt and relatedly, sea level rise. We find that the EnKF improves model runs initialized using incorrect ini

Shadow-based matching for robust absolute localization during lunar landings

Autor: Kaufmann, Hannah

The exploration of the moon can give insights to the evolution and history of the solar system. Future lunar exploration missions require autonomous, safe and precise landings close to scientific spots of interest. Currently the German Aerospace Cent
