Formal loops II: A local Riemann-Roch theorem for determinantal gerbes
M. Kapranov, E. Vasserot
If V is a bundle of Tate vector spaces over a base B, its determinantal gerbe has a class C_1(V) in the second cohomology group of the sheaf of invertible functions which can be se…
Minimizing Constant Mean Curvature Hypersurfaces in Hyperbolic Space
Baris Coskunuzer
We study the constant mean curvature (CMC) hypersurfaces in hyperbolic space whose asymptotic boundaries are closed codimension-1 submanifolds in sphere at infinity. We consider CM…
A High Resolution HI Study of Selected Virgo Galaxies - Preliminary Results on Gas Morphology & Extra-Planar Gas
Aeree Chung, J. H. van Gorkom, Jeffery D. P. Kenney +1
We present preliminary results of VLA HI imaging of selected Virgo cluster galaxies. The goal is to study environmental effects on galaxy evolution. Our sample of 41 galaxies is sp…
Counting overlattices in automorphism groups of trees
Seonhee Lim
We give an upper bound for the number of ``overlattices'' in the automorphism group of a tree, containing a fixed lattice with index n. For an example of a lattice in the automorph…
On the intersection theory of the moduli space of rank two bundles
Alina Marian, Dragos Oprea
We give an algebro-geometric derivation of the known intersection theory on the moduli space of stable rank 2 bundles of odd degree over a smooth curve of genus g. We lift the comp…
Modules over the small quantum group and semi-infinite flag manifold
S. Arkhipov, R. Bezrukavnikov, A. Braverman +2
We develop a theory of perverse sheaves on the semi-infinite flag manifold , and show that the subcategory of Iwahori-monodromy perverse sheaves is equiv…
