Relativity, Causality, Locality, Quantization and Duality in the Invariant Generalized Space-Time
M. A. Vasiliev
We analyze properties of the Sp(2M) conformally invariant field equations in the recently proposed generalized $\half M(M+1)$-dimensional space-time $\M_M$ with matrix coordinates.…
Constraint Reorganization Consistent with the Dirac Procedure
D. M. Gitman, I. V. Tyutin
The way of finding all the constraints in the Hamiltonian formulation of singular (in particular, gauge) theories is called the Dirac procedure. The constraints are naturally class…
Stability of two-fermion bound states in the explicitly covariant Light-Front Dynamics
M. Mangin-Brinet, J. Carbonell, V. A. Karmanov
The covariant light-front equations have been solved exactly for a two fermion system with different boson exchange ladder kernels. We present a method to study the cutoff dependen…
Type IIB Green-Schwarz superstring in plane wave Ramond-Ramond background
R. R. Metsaev
We construct the covariant -symmetric superstring action for type superstring on plane wave space supported by Ramond-Ramond background. The action is defined as a 2d sigm…
On the theory of scalar pair production by a potential barrier
A. I. Nikishov
The problem of the scalar pair production by a one-dimensional vector- potential is reduced to the matrix formalism of the theory with an unstable vacuum. Our choic…
Point particle in general background fields vs. free gauge theories of traceless symmetric tensors
A. Yu. Segal
Point particle may interact to traceless symmetric tensors of arbitrary rank. Free gauge theories of traceless symmetric tensors are constructed, that provides a possibility for a…
Nonperturbative renormalization in a scalar model within Light-Front Dynamics
D. Bernard, Th. Cousin, V. A. Karmanov +1
Within the covariant formulation of Light-Front Dynamics, in a scalar model with the interaction Hamiltonian , we calculate nonperturbatively the renormalized sta…
Integrable Structure of the Dirichlet Boundary Problem in Two Dimensions
A. Marshakov, P. Wiegmann, A. Zabrodin
We study how the solution of the two-dimensional Dirichlet boundary problem for smooth simply connected domains depends upon variations of the data of the problem. We show that the…
Associativity Equations in Effective SUSY Quantum Field Theories
A. Marshakov
The role of associativity or WDVV equations in effective supersymmetric quantum theories is discussed and it is demonstrated that for wide class of their solutions when residue for…
Stability of bound states in the light-front Yukawa model
V. A. Karmanov, J. Carbonell, M. Mangin-Brinet
We show that in the system of two fermions interacting by scalar exchange, the solutions for J= bound states are stable without any cutoff regularization, for values of th…
Relativistic bound states in Yukawa model
M. Mangin-Brinet, J. Carbonell, V. A. Karmanov
The bound state solutions of two fermions interacting by a scalar exchange are obtained in the framework of the explicitly covariant light-front dynamics. The stability with respec…
Free fermionic higher spin fields in AdS(5)
K. B. Alkalaev
Totally symmetric massless fermionic fields of arbitrary spins in AdS(5) are described as su(2,2) multispinors. The approach is based on the well-known isomorfism o(4,2)=su(2,2). E…
Braneworld effective action and origin of inflation
A. O. Barvinsky
We construct braneworld effective action in two brane Randall-Sundrum model and show that the radion mode plays the role of a scalar field localizing essentially nonlocal part of t…
p,q-Duality and Hamiltonian Flows in the Space of Integrable Systems or Integrable Systems as Canonical Transforms of the Free Ones
A. Mironov, A. Morozov
Variation of coupling constants of integrable system can be considered as canonical transformation or, infinitesimally, a Hamiltonian flow in the space of such systems. Any functio…
Electric-Magnetic Duality and WDVV Equations
B. de Wit, A. Marshakov
We consider the associativity (or WDVV) equations in the form they appear in Seiberg-Witten theory and prove that they are covariant under generic electric-magnetic duality transfo…

M. A. Vasiliev
The dynamics of totally symmetric free massless higher spin fields in is reformulated in terms of the compensator formalism for AdS gravity. The higher spin algebra…
Seiberg-Witten maps from the point of view of consistent deformations of gauge theories
G. Barnich, M. Grigoriev, M. Henneaux
Noncommutative versions of theories with a gauge freedom define (when they exist) consistent deformations of their commutative counterparts. General aspects of Seiberg-Witten maps…
Conformal Higher Spin Symmetries of 4d Massless Supermultiplets and Invariant Equations in Generalized (Super)Space
M. A. Vasiliev
Realization of the conformal higher spin symmetry on the 4d massless field supermultiplets is given. The self-conjugated supermultiplets, including the linearized SYM…
On Associativity Equations in Dispersionless Integrable Hierarchies
A. Boyarsky, A. Marshakov, O. Ruchayskiy +2
We discuss the origin of the associativity (WDVV) equations in the context of quasiclassical or Whitham hierarchies. The associativity equations are shown to be encoded in the disp…

Sumit R. Das, Andrei Zelnikov
A uniformly acclerated observer in anti-deSitter space-time is known to detect thermal radiation when the acceleration exceeds a critical value. We investigate the holographic inte…
