X-ray flares following short gamma-ray bursts from shock heating of binary stellar companions
Andrew I. MacFadyen, Enrico Ramirez-Ruiz, Weiqun Zhang
The discovery of long-lasting (~100 s) X-ray flares following short gamma-ray bursts initially called into question whether they were truly classical short-hard bursts. Opinion ove…
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…
The redshift distribution of gamma-ray bursts revisited
Priyamvada Natarajan, Badr Albanna, Jens Hjorth +3
In this letter, we calculate the redshift distribution of gamma-ray bursts assuming that they trace (i) the globally averaged star formation rate or (ii) the average metallicity in…
Isospectral Cayley graphs of some finite simple groups
Alexander Lubotzky, Beth Samuels, Uzi Vishne
We apply spectral analysis of quotients of the Bruhat-Tits buildings of type to construct isospectral non-isomorphic Cayley graphs of the finite simple groups $\o…
On the preservation of absolutely continuous spectrum for Schrodinger operators
Sergey A. Denisov
We present general principles for the preservation of a.c. spectrum under weak perturbations. The Schrodinger operators on the strip and on the Caley tree (Bethe lattice) are consi…
