Non-abelian cubic vertices for higher-spin fields in anti-de Sitter space
Nicolas Boulanger, Dmitry Ponomarev, E. D. Skvortsov
We use the Fradkin-Vasiliev procedure to construct the full set of non-abelian cubic vertices for totally symmetric higher spin gauge fields in anti-de Sitter space. The number of…
Quantum corrections to spinning superstrings in AdS_3 x S^3 x M^4: determining the dressing phase
M. Beccaria, F. Levkovich-Maslyuk, G. Macorini +1
We study the leading quantum string correction to the dressing phase in the asymptotic Bethe Ansatz system for superstring in AdS_3 x S^3 x T^4 supported by RR flux. We find that t…
Asymptotic Hurwitz numbers
A. Mironov, A. Morozov, S. Natanzon
The classical Hurwitz numbers of degree n together with the Hurwitz numbers of the seamed surfaces of degree n give rise to the Klein topological field theory. We extend this const…
Multiparticle extension of the higher-spin algebra
M. A. Vasiliev
Multiparticle extension of a higher-spin algebra is introduced as the Lie superalgebra associated with the universal enveloping algebra . While conventional higher-spin s…
Lattice W-algebras and logarithmic CFTs
A. M. Gainutdinov, H. Saleur, I. Yu. Tipunin
This paper is part of an effort to gain further understanding of 2D Logarithmic Conformal Field Theories (LCFTs) by exploring their lattice regularizations. While all work so far h…
Knot polynomials in the first non-symmetric representation
A. Anokhina, A. Mironov, A. Morozov +1
We describe the explicit form and the hidden structure of the answer for the HOMFLY polynomial for the figure eight and some other 3-strand knots in representation [21]. This is th…
Reparametrization-Invariant Effective Action in Field-Antifield Formalism
Igor A. Batalin, Klaus Bering
We introduce classical and quantum antifields in the reparametrization-invariant effective action, and derive a deformed classical master equation.
Conformal totally symmetric arbitrary spin fermionic fields
R. R. Metsaev
Conformal totally symmetric arbitrary spin fermionic fields propagating in the flat space-time of even dimension greater than or equal to four are investigated. First-derivative me…
Cardy-Frobenius extension of algebra of cut-and-join operators
A. Mironov, A. Morozov, S. Natanzon
Motivated by the algebraic open-closed string models, we introduce and discuss an infinite-dimensional counterpart of the open-closed Hurwitz theory describing branching coverings…
Correlation functions and spectral curves in models of minimal gravity
O. Kruglinskaya
The correlation functions for models of minimal gravity are discussed. An algorithm is proposed for calculations of invariant ratios from formulas of residues that can be compared…
New representation of the nonlocal ghost-free gravity theory
A. O. Barvinsky, Yu. V. Gusev
A new representation is found for the action of the recently suggested ghost-free nonlocal gravity models generating de Sitter or Anti-de Sitter background with an arbitrary value…
Nonlinear magnetic response of the magnetized vacuum to applied electric field
Dmitry M. Gitman, Anatoly E. Shabad
We find first nonlinear correction to the field, produced by a static charge at rest in a background constant magnetic field. It is quadratic in the charge and purely magnetic. The…
Massless hook field in AdS(d+1) from the holographic perspective
K. B. Alkalaev
We systematically consider the AdS/CFT correspondence for a simplest mixed-symmetry massless gauge field described by hook Young diagram. We introduce the radial gauge fixing and e…
Exact higher-spin symmetry in CFT: all correlators in unbroken Vasiliev theory
V. E. Didenko, E. D. Skvortsov
All correlation functions of conserved currents of the CFT that is dual to unbroken Vasiliev theory are found as invariants of higher-spin symmetry in the bulk of AdS. The conforma…
A Hurwitz theory avatar of open-closed strings
A. Mironov, A. Morozov, S. Natanzon
We review and explain an infinite-dimensional counterpart of the Hurwitz theory realization of algebraic open-closed string model a la Moore and Lizaroiu, where the closed and open…
Conformal blocks of Chiral fields in N=2 SUSY CFT and Affine Laumon Spaces
V. Belavin
We consider the problem of computing N=2 superconformal block functions. We argue that the Kazama-Suzuki coset realization of N=2 superconformal algebra in terms of the affine sl(2…
On suppression of topological transitions in quantum gravity
A. O. Barvinsky
We discuss the effect of dynamical suppression for a special class of topological configurations in cosmology, which occur in Euclidean quantum gravity (EQG) when the latter is vie…
Towards higher-spin holography in ambient space of any dimension
V. E. Didenko, E. D. Skvortsov
We derive the propagators for higher-spin master fields in anti-de Sitter space of arbitrary dimension. A method is developed to construct the propagators directly without solving…
Lie Groups, Cluster Variables and Integrable Systems
A. Marshakov
We discuss the Poisson structures on Lie groups and propose an explicit construction of the integrable models on their appropriate Poisson submanifolds. The integrals of motion for…
Noncommutative magnetic moment, fundamental length and lepton size
T. C. Adorno, D. M. Gitman, A. E. Shabad
Upper bounds on fundamental length are discussed that follow from the fact that a magnetic moment is inherent in a charged particle in noncommutative (NC) electrodynamics. The stro…
Notes on the ambient approach to boundary values of AdS gauge fields
Xavier Bekaert, Maxim Grigoriev
The ambient space of dimension d+2 allows to formulate both fields on AdS(d+1) and conformal fields in d dimensions such that the symmetry algebra o(d,2) is realized linearly. We e…
Mixed-symmetry tensor conserved currents and AdS/CFT correspondence
K. B. Alkalaev
We present the full list of conserved currents built of two massless spinor fields in Minkowski space and their derivatives multiplied by Clifford algebra elements. The currents ha…

A. Anokhina, A. Mironov, A. Morozov +1
Basing on evaluation of the Racah coefficients for SU_q(3) (which supported the earlier conjecture of their universal form) we derive explicit formulas for all the 5-, 6- and 7-str…
