#### Undergraduate Mathematics Research Seminar

When: 2:30-3:20pm Thursdays

Where: Zoom link.

The Undergraduate Mathematics Research Seminar (UMRS) is a seminar hosted by the University of Minnesota math department for undergraduates pursuing research, interested in research, or who are just interested in learning more mathematics. For the 2020-2021 semester the seminar will be held online and we welcome those interested from outside universities. If you’d like to be on the mailing list or want to give a talk, see my contact page. To see the 2019-2020 schedule see here and for the 2018-2019 schedule see here.

- Oct. 1st: Henry Twiss – Combinatorics in the alcove walk model

The alcove walk model is a combinatorial tool used to compute special integrals by partitioning a vector space into *alcoves*. A walk is then a sequence of steps across adjacent alcoves, and there is a natural notion of *folded walks*. We will introduce the construction of the alcove walk model in the plane, the notion of folded walks, and discuss some of their properties to better understand how certain walks in the alcove walk model can occur. If you enjoy looking at tessellations of the plane into triangles and hexagons, you will love this talk! Much of this work was done during the UMN 2020 REU in Algebra, Combinatorics, and Representation Theory.

- Oct. 29th: Tony Travia – Wavelets, time-frequency localization, and applications in solid state theoretical physics (tentative topic)
- Nov. 12th: Zachary Deiman – Strip patterns and generalizations of the Swify-Hohenberg equation (tentative topic)

#### Undergraduate Mathematics Virtual Lounge

When: Every weekday 11am-5pm.

Where: Zoom link.

The Undergraduate Mathematics Virtual Lounge is a zoom room where mathematics undergraduates from the University of Minnesota can get together to socialize, group study, ask questions, and exchange advice about excelling in the program. The zoom link will be open from 11am-5pm on weekdays. Sometimes we will host events. If you’d like to be on the mailing list, see my contact page.
