in Computational science, Mathematics And Physics

ZUCCMAP will start taking place in the 3rd week of Spring semester on **Tuesdays** from **12:15 to 13:00** in **HG G5**, with every talk followed by an apéro!

If you want to give a talk, please fill this form.

**Graphs Can Have Eigenvalues - and They Mean a Lot **

** Abstract: ** A very friendly introduction to spectral graph theory and some algorithms this theory gives rise to which are known to be optimal approximation algorithms to NP-hard problems.

We run a weekly colloquium where students present topics from diverse areas in mathematics and physics.

**The talks are followed by an Apéro**, giving you the chance to mingle in informal atmosphere over some delicious food!

All talks are aimed at undergraduate students (from the first semester on!), so don’t let the titles scare you! Who knows, maybe you’ll find a topic for your Bachelor’s thesis or other independent work!

**12.03**- Matthias Bonvin:*Group Theory for Neural Network***19.03**- Lukas Münzel:*Progress, Machine Learning, and Why to Be Optimistic About the Future***26.03**- Daniel Gotsmann:*Stellar Spectroscopy and Classifying Stars***09.04**- Jonatan Wächter:*Scaling Limits of Grid Curves, in Particular Some Non-Markovian Models***16.04**- Esty Gusak:*A Friendly Introduction to Isogeny Cryptography***23.04**- Mert Ünsal:*Graphs Can Have Eigenvalues - and They Mean a Lot***07.05**- Nicolas Hotton:*Beyond CLT, how wild can random eigenvalues behave?***14.05**- Alexandre Faroux:*Better than Einstein ? On Bachelier’s Theory of Speculation***21.05**- Jessica Prendi:*How Do We Discover New Physics?*

Giving talks is a critical part of any scientist's career and so presenting to a group of fellow students in a familiar environment, is an easy way to get started. We also hope to provide a platform for students to practice their presentation with a live audience before their thesis defense. If you’re interested in giving a talk, please fill this form.

ZUCCMAP was initiated in autumn 2020 by Alexander Uhlmann, Jinghao Cao, and Silvio Barandun. Later, it has been organized by all ETH students below:

- Birnick, Siddharth Setlur (Spring 2022)
- Alessandra Iacopino, Ana Pavlaković (Autumn 2022)
- Thibault Vignon, Philémon Borderaux (Spring 2023)
