Speaker: Ernesto Lupercio, Cinvestav, Mexico

Title: On the moduli space for Quantum Toric Varieties

Abstract: Just as the quantum torus generalizes the ordinary commutative torus, quantum toric varieties generalize ordinary ones. But unlike ordinary ones, quantum torics form moduli spaces with a rich structure. In this talk I will describe these spaces and some examples of its compactifications. Joint work with Katzarkov, Meersseman, and Verjosky.

Algebra and Combinatorics Seminar

iCal  iCal

Time: 3:00PM - 4:00PM

Location: Zoom

Speaker: Guoli Ding, Louisiana State University

Title: New results on unavoidable large graphs

Abstract: Ramsey theorem states that a large clique or coclique is unavoidable in every sufficiently large graph. This result can be extended to graphs of other connectivity. For instance, a big W_n- or K_{3,n}-minor is unavoidable in every sufficiently large 3-connected graph. In this talk we present similar results including results for rooted graphs.
