Research-Oriented Seminar In COmbinatorics (ROSICO)
This is a reading seminar for PhD students and researchers. The topic changes every year/semester. It includes free coffee breaks.
If you are interested in participating, please send an email to cult-owner@lists.dm.unipi.it, bring your coffee cup/mug/water bottle, and be ready to give a talk!
The topic of the second semester of this year is "Integrable systems and combinatorics". We will extract our reading material from the following sources:
[D] Deift "Integrable Systems and Combinatorial Theory", pdf
[W] Wolf " Random Matrix Theory: A Combinatorial Proof of Wigner's Semicircle Law ", link
[Z] Zvonkin "Matrix integrals and map enumeration: an accessible introduction", pdf
