Ethiopia has a long and complex history with Jews and Judaism.
Perhaps most constitutive of the connection between the two is an
Ethiopian tradition according to which the favor of the God of
Israel, along with the ark of the covenant, was...
It’s been a fantastic decade for black hole studies, highlighted
by the 2017 and 2020 Nobel Prizes in Physics. Multiple Galactic
Center research groups, the Event Horizon Telescope, and LIGO/Virgo
continue to bring rapid-fire new observations to...
We construct an explicit isomorphism between certain truncations
of quiver Hecke algebras and Elias-Williamson's diagrammatic
endomorphism algebras of Bott-Samelson bimodules. As a corollary,
we deduce that the decomposition numbers of these...
The Picard group of the stable module category of a finite group
plays a role in many parts of modular representation theory. It was
calculated when the group is an abelian p-group, by pioneering work
of Dade in the 1970's, and a classification for...
We explain an equivalence of categories between a module
category of quiver Hecke algebras associated with the Kronecker
quiver and a category of equivariant perverse coherent sheaves on
the nilpotent cone of type A. This provides a link between
two...
The geometric Satake equivalence establishes a link between two
categories: the category of spherical perverse sheaves on the
affine Grassmannian and the category of representations of the
Langlands dual group. It has found many important...
In the theory of turbulence, a famous conjecture of Onsager
asserts that the threshold Hölder regularity for the total kinetic
energy conservation of (spatially periodic) Euler flows is 1/3. In
particular, there are Hölder continuous Euler flows...
There are two categorical realizations of the affine Hecke
algebra: constructible sheaves on the affine flag variety and
coherent sheaves on the Langlands dual Steinberg variety. A
fundamental problem in geometric representation theory is to
relate...
