Generalized Kazakov-Migdal-Kontsevich Model: group theory aspects
S. Kharchev, A. Marshakov, A. Mironov +1
The Kazakov-Migdal model, if considered as a functional of external fields, can be always represented as an expansion over characters of group. The integration over "matter fi…
Quantum Group and Magnetic Translations. Bethe-Ansatz Solution for Azbel-Hofstadter Problem
P. B Wiegmann, A. V. Zabrodin
We present a new approach to the problem of Bloch electrons in magnetic ( sometimes called Azbel-Hofstadter problem) field, by making explicit a natural relation between the group…
Dark Matter Annihilations in the Large Magellanic Cloud
P Gondolo
The flat rotation curve obtained for the outer star clusters of the Large Magellanic Cloud is suggestive of an LMC dark matter halo. From the composite HI and star cluster rotation…
On the Infrared Limit of Two Dimensional QCD
A. J. Niemi, P. Pasanen
We study the infrared limit of two dimensional QCD, with massless dynamical Dirac fermions that are in the fundamental representation of the gauge group. We find that the theory re…
Symplectic structure of the moduli space of flat connections on a Riemann surface
A. Yu. Alekseev, A. Z. Malkin
We consider canonical symplectic structure on the moduli space of flat ${\g}$-connections on a Riemann surface of genus with marked points. For ${\g}$ being a semisimple Li…
Symplectic Geometry of Supersymmetry and Nonlinear Sigma Model
Kaupo Palo
Recently it has been argued, that Poincaré supersymmetric field theories admit an underlying loop space hamiltonian (symplectic) structure. Here shall establish this at the level o…
On kinematical constraints in Regge calculus
V. Khatsymovsky
In the (3+1)D Hamiltonian Regge calculus (one of the coordinates, , is continuous) conjugate variables are (defined on triangles of discrete 3D section ) finite conne…
On quantization of Regge links
V. Khatsymovsky
In quantum Regge calculus areas of timelike triangles possess discrete spectrum. This is because bivectors of these triangles are variables canonically conjugate to orthogonal conn…
How to construct quantum measure in Regge calculus?
V. Khatsymovsky
We propose the following way of constructing quantum measure in Regge calculus: the full discrete Regge manifold is made continuous in some direction by tending corresponding dimen…
Can wormholes exist?
V. Khatsymovsky
Renormalized vacuum expectation values of electromagnetic stress-energy tensor are calculated in the background spherically-symmetrical metric of the wormhole's topology. Covariant…
Stability Analysis of Sum Rules for Compton Scattering
Claudio Coriano', Hsiang-nan Li
We perform a stability analysis of a recently proposed sum rule for pion Compton scattering at fixed angle and moderate Mandelstam invariants. The sum rule is found to be sensitive…
The birth of the giant component
Svante Janson, Donald E. Knuth, Tomasz Łuczak +1
Limiting distributions are derived for the sparse connected components that are present when a random graph on vertices has approximately $\half n$ edges. In particular, we sho…
On Quantum Integrability and the Lefschetz Number
A. J. Niemi, K. Palo
Certain phase space path integrals can be evaluated exactly using equivariant cohomology and localization in the canonical loop space. Here we extend this to a general class of mod…
Decorated-box-diagram-contributions to Bhabha scattering. (II)
Göran Fäldt, Per Osland
We evaluate, in the high-energy limit, , the sum of amplitudes corresponding to a class of Feynman diagrams describing two-loop virtual photonic corrections t…
Hamiltonian systems of Calogero type and two dimensional Yang-Mills theory
A. Gorsky, N. Nekrasov
We obtain integral representations for the wave functions of Calogero-type systems,corresponding to the finite-dimentional Lie algebras,using exact evaluation of path integral.We g…

Ward identities and W-constraints in Generalized Kontsevich Model
A. Mikhailov
The connection is obtained between Ward identities and W-constraints in Generalized Kontsevich Model with the potential . We show that Ward identities include W-constraints…
Symplectic structures associated to Lie-Poisson groups
A. Yu. Alekseev, A. Z. Malkin
The Lie-Poisson analogues of the cotangent bundle and coadjoint orbits of a Lie group are considered. For the natural Poisson brackets the symplectic leaves in these manifolds are…
Degenerations of Sklyanin algebra and Askey-Wilson polynomials
A. S. Gorsky, A. V. Zabrodin
A new trigonometric degeneration of the Sklyanin algebra is found and the functional realization of its representations in space of polynomials in one variable is studied. A furthe…
