On the Frame-Like Formulation of Mixed-Symmetry Massless Fields in (A)dS(d)
K. B. Alkalaev, O. V. Shaynkman, M. A. Vasiliev
The frame-like covariant Lagrangian formulation of bosonic and fermionic mixed-symmetry type higher spin massless fields propagating on the AdS(d) background is proposed. Higher sp…

R. R. Metsaev
Free totally symmetric arbitrary spin massive bosonic and fermionic fields propagating in AdS(d) are investigated. Using the light cone formulation of relativistic dynamics we stud…

Cohomology spaces of the Poisson superalgebra realized on smooth Grassmann-valued functions with compact support on ($C^{2n}) are investigated under suitable continuity re…

K. B. Alkalaev
Particular class of AdS(d) mixed-symmetry bosonic massless fields corresponding to arbitrary two-column Young tableaux is considered. Unique gauge invariant free actions are found…

Within the framework of the covariant formulation of Light-Front Dynamics, we develop a nonperturbative renormalization scheme in the fermion model supposing that the composite fer…
Hamiltonian BRST and Batalin-Vilkovisky formalisms for second quantization of gauge theories
Glenn Barnich, Maxim Grigoriev
Gauge theories that have been first quantized using the Hamiltonian BRST operator formalism are described as classical Hamiltonian BRST systems with a BRST charge of the form <Ψ,ΩΨ…
Partition Functions of Matrix Models as the First Special Functions of String Theory I. Finite Size Hermitean 1-Matrix Model
A. Alexandrov, A. Mironov, A. Morozov
Even though matrix model partition functions do not exhaust the entire set of tau-functions relevant for string theory, they seem to be elementary building blocks for many others a…
The symmetry, inferable from Bogoliubov transformation, between the processes induced by the mirror in two-dimentional and the charge in four-dimentional space-time
V. I. Ritus
The symmetry between the creation of pairs of massless bosons or fermions by accelerated mirror in 1+1 space and the emission of single photons or scalar quanta by electric or scal…

Igor Batalin, Igor Tyutin
By explicit calculation of the effect of a ghost-dependent canonical transformation of BRST-charge, we derive the corresponding transformation law for structure coefficients of ham…
Integrable Structure of the Dirichlet Boundary Problem in Multiply-Connected Domains
I. Krichever, A. Marshakov, A. Zabrodin
We study the integrable structure of the Dirichlet boundary problem in two dimensions and extend the approach to the case of planar multiply-connected domains. The solution to the…
Two-fermion relativistic bound states in Light-Front Dynamics

In the Light-Front Dynamics, the wave function equations and their numerical solutions, for two fermion bound systems, are presented. Analytical expressions for the ladder one-boso…

We consider the Dirac equation with a magnetic-solenoid field (the superposition of the Aharonov--Bohm solenoid field and a collinear uniform magnetic field). Using von Neumann's t…
