Joint IAS/PU Symplectic Geometry Seminar

Sectorial Decompositions of Symmetric Products and Homological Mirror Symmetry
Clair Xinle Dai
1:00pm|Fine Hall 401

Symmetric products of Riemann surfaces play a crucial role in symplectic geometry and low-dimensional topology. They are key to defining Heegaard Floer homology and serve as important examples of Liouville manifolds when the surfaces are open. In...

Computer Science/Discrete Mathematics Seminar II

Approximate Covers and Cocycle Expansion
Irit Dveer Dinur
10:30am|Simonyi Hall 101 and Remote Access

I will talk about the well known relation between cocycles and covers.  Then, I will discuss the relation of cocycle expansion to approximate covers, and finally how these show up in low-soundness PCP agreement tests.

The Cyclosyntomic Regulator of a Number Field
Tess Bouis
3:30pm|Simonyi 101 and Remote Access

The regulator of a number field is defined in terms of values of the logarithm function evaluated at units of this number field. Similarly, one can define the p-adic regulator of a number field in terms of the p-adic logarithm, and this p-adic...
