In category theory, a category with a terminal object is well-pointed if for every pair of arrows such that , there is an arrow such that . (The arrows are called the global elements or points of the category; a well-pointed category is thus one that has "enough points" to distinguish non-equal arrows.) (Wikipedia).

Learn all about angles. An angle is a figure formed by two rays sharing a common endpoint. An angle can be classified as acute, right, obtuse, straight or refrex. An acute angle is an angle which measures less than 90 degrees. A right angle measures 90 degrees. An obtuse angle measures mor

Partially wrapped Fukaya categories of symmetric products of marked disks, Gustavo Jasso
Partially wrapped Fukaya categories of symmetric products of marked surfaces were in- troduced by Auroux so as to give a symplecto-geometric intepretation of the bordered Heegaard-Floer homology of Lipshitz, Ozsv ́ath and Thurston. In this talk, I will explain the equivalence between the p

Clark Barwick - 1/3 Exodromy for ℓ-adic Sheaves
In joint work with Saul Glasman and Peter Haine, we proved that the derived ∞-category of constructible ℓ-adic sheaves ’is’ the ∞-category of continuous functors from an explicitly defined 1-category to the ∞-category of perfect complexes over ℚℓ. In this series of talks, I want to offer s

D. Gaitsgory - "fundamental local equivalence" for quantum geometric Langlands
The key role in the usual geometric Langlands is played by the geometric Satake equivalence, which says that the category of spherical perverse sheaves on the affine Grassmannian Gr_G of the group G is equivalent to the category Rep(G^L) of algebraic representations of the Langlands dual G
