# Geometric group theory seminar

### Spring 2020

The geometric group theory seminar will be starting next week. It will run on Fridays, 2:30-3:20 in Keller 402. Our first speaker will be Inkang Kim from the Korean institute of advanced study who will speak about primitive stable representations. Please let me know if you are interested in being part of our seminar mailing list. Asaf Hadari https://math.hawaii.edu/~hadari/

### Fall 2019

We will begin the Geometric Group Theory seminar again in a couple of weeks. This semester it will take place on Tuesdays at 3pm in Keller 301. If you are interested in attending please email Andrew Sale to be added to the mailing list. We will work up towards a proof of $\delta$-hyperbolicity of the curve complex of a graph, and we hope to make it accessible to grad students, especially those who have had some exposure to GGT. If you have any questions about what we will cover, don’t hesitate to email. Thanks for reading and hope to see you there!

# Identifiability and Inference for Phylogenetic Networks using Applied Algebraic Geometry

Assistant Professor Elizabeth Gross has been awarded a CAREER grant from NSF in the amount of \$464,828. Some more details can be found here: Identifiability and Inference for Phylogenetic Networks using Applied Algebraic Geometry.

She previously studied Computational algebraic geometry and combinatorial algorithms for neuroscience and biological networks under another NSF award.

# Logic Seminar Spring 2020

The logic seminar for Spring 2020 will be held Fridays at 2:30–3:20pm, room TBA.
The logic seminar for Fall 2019 was held Wednesdays at 2:30–3:20pm in Keller 314.
