A 1948 theorem of de Bruijn and Erdős says that
if nn points in a projective plane do not lie all on a
line, then they determine at least n lines. More generally, Dowling
and Wilson conjectured in 1974 that for any finite set of vectors
spanning a...
Non-constructive existence proofs, which establish the existence
of objects without furnishing an efficient algorithm to produce
examples, abound in mathematics. How hard is it, computationally,
to find objects whose existence is guaranteed non...
The purpose of this talk is to explore how Lagrangian Floer
homology groups change under (non-Hamiltonian) symplectic isotopies
on a (negatively) monotone symplectic
manifold (M,ω)(M,ω) satisfying a strong non-degeneracy
condition. More precisely...
Binary neutron star mergers provide a unique probe of the
neutron star equation of state (EOS) across a wide range of
parameter space, from the zero-temperature EOS during the inspiral
to the finite-temperature EOS following the merger. In this
talk...

In the upcoming series of talks we discuss some equivalences by
Bezrukavnikov between categories of coherent sheaves on Steinberg
varieties and of perverse sheaves on the affine flag variety. In
this talk I discuss the decategorified isomorphism...
