Comment on the Calculation of the Angular Momentum and Mass for the (Anti-) Self Dual Charged Spinning Black Hole
A recent paper [M. Kamata and T. Koikawa, Phys. Lett. {\bf B353} (1995) 196.]
claimed to obtain the charged version of the -dimensional spinning
black hole solution by assuming a (anti-) self dual condition imposed on the
electric and magnetic fields. We point out that the angular momentum and mass
diverge at spatial infinity and as a consequence the solution is unphysicalComment: 4 pages, Latex, no figures, final version to be publised in Phys.

High-energy String Scatterings of Compactified Open String
We calculate high-energy massive string scattering amplitudes of compactified
open string. We derive infinite linear relations, or stringy symmetries, among
soft high-energy string scattering amplitudes of different string states in the
Gross kinematic regime (GR). In addition, we systematically analyze all hard
power-law and soft exponential fall-off regimes of high-energy compactified
open string scatterings by comparing the scatterings with their 26D
noncompactified counterparts. In particular, we discover the existence of a
power-law regime at fixed angle and an exponential fall-off regime at small
angle for high-energy compactified open string scatterings. The linear
relations break down as expected in all power-law regimes. The analysis can be
extended to the high-energy scatterings of the compactified closed string,
which corrects and extends the previous results in [28] .Comment: 16 pages, 1 table. v2:typos corrected,references added. v3,v4:Eq.(26)

Deligne-Lusztig Constructions for Division Algebras and the Local Langlands Correspondence
Let be a local non-Archimedean field of positive characteristic and let
be the degree- unramified extension of . Via the local Langlands and
Jacquet-Langlands correspondences, to each sufficiently generic multiplicative
character of , one can associate an irreducible representation of the
multiplicative group of the central division algebra of invariant
over .
In 1979, Lusztig proposed a cohomological construction of supercuspidal
representations of reductive -adic groups analogous to Deligne-Lusztig
theory for finite reductive groups. In this paper we prove that when , the
-adic Deligne-Lusztig (ind-)scheme induces a correspondence between
smooth one-dimensional representations of and representations of
that matches the correspondence given by the LLC and JLC.Comment: 61 pages. Version 2: minor revision
