Off-shell higher-spin fields in and external currents
N. G. Misuna
We construct an unfolded system for off-shell fields of arbitrary integer spin in 4d anti-de Sitter space. To this end we couple an on-shell system, encoding Fronsdal equations, to…
Elliptic matrix models
A. Mironov, A. Morozov
The Gaussian matrix model is known to deform to the -matrix model. We consider further deformation to the elliptic matrix model by properly deforming the Gaussian densit…
Towards elliptic deformation of -matrix models
A. Mironov, A. Morozov
As a necessary step in constructing elliptic matrix models, which preserve the superintegrability property , we suggest an elliptic deformation of the peculi…
Superintegrability of Kontsevich matrix model
A. Mironov, A. Morozov
Many eigenvalue matrix models possess a peculiar basis of observables which have explicitly calculable averages. This explicit calculability is a stronger feature than ordinary int…
Anticanonical transformations and Grand Jacobian
I. A. Batalin, P. M. Lavrov, I. V. Tyutin
An independent (purely algebraic) proof of factorization property of the Grand Jacobian corresponding to anticanonical transformations in the BV-formalism is given.
Dual description of -deformed OSP sigma models
Mikhail Alfimov, Boris Feigin, Ben Hoare +1
We study the dual description of the -deformed sigma model in the asymptotically free regime (). Compared to the case of classical Lie groups, for supergroup…
Algebra of quantum -polynomials
A. Mironov, A. Morozov
Knot polynomials colored with symmetric representations of satisfy difference equations as functions of representation parameter, which look like quantization of classica…
Spin-Locality of and Quartic Higher-Spin Vertices
V. E. Didenko, O. A. Gelfond, A. V. Korybut +1
Higher-spin theory contains a complex coupling parameter . Different higher-spin vertices are associated with different powers of and its complex conjugate . Using $…
Presymplectic AKSZ formulation of Einstein gravity
Maxim Grigoriev, Alexei Kotov
Any local gauge theory can be represented as an AKSZ sigma model (upon parameterization if necessary). However, for non-topological models in dimension higher than 1 the target spa…
Sigma models with local couplings: a new integrability -- RG flow connection
Ben Hoare, Nat Levine, Arkady A. Tseytlin
We consider several classes of -models (on groups and symmetric spaces, -models, -models) with local couplings that may depend on the 2d coordinates, e.g. on time . We…
Distinguishing Mutant Knots
L. Bishler, Saswati Dhara, T. Grigoryev +6
Knot theory is actively studied both by physicists and mathematicians as it provides a connecting centerpiece for many physical and mathematical theories. One of the challenging pr…
More on Wilson toroidal networks and torus blocks
K. B. Alkalaev, V. A. Belavin
We consider the Wilson line networks of the Chern-Simons gravity theory with toroidal boundary conditions which calculate global conformal blocks of degenerate quasi-primary o…
A Stringy theory in three dimensions and Massive Higher Spins
Evgeny Skvortsov, Tung Tran, Mirian Tsulaia
An example of a consistent theory with massive higher spin fields is constructed in flat space-time of dimension three. The action is written in the light-cone gauge. The theory ha…
Cubic interactions of arbitrary spin fields in 3d flat space
R. R. Metsaev
Using light-cone gauge formulation, massive arbitrary spin irreducible fields and massless (scalar and one-half spin) fields in three-dimensional flat space are considered. Both th…
Characteristic Cohomology and Observables in Higher Spin Gravity
Alexey Sharapov, Evgeny Skvortsov
We give a complete classification of dynamical invariants in and Higher Spin Gravity models, with some comments on arbitrary . These include holographic correlation fu…
Perspectives of differential expansion
L. Bishler, A. Morozov
We outline the current status of the differential expansion (DE) of colored knot polynomials i.e. of their -- decomposition into representation-- and knot--dependent parts. I…
On matter-free Higher Spin Gravities in 3d: (partially)-massless fields and general structure
Maxim Grigoriev, Karapet Mkrtchyan, Evgeny Skvortsov
We study the problem of interacting theories with (partially)-massless and conformal higher spin fields without matter in three dimensions. A new class of theories that have partia…
Elliptic lift of the Shiraishi function as a non-stationary double-elliptic function
H. Awata, H. Kanno, A. Mironov +1
As a development of arXiv:1912.12897, we note that the ordinary Shiraishi functions have an insufficient number of parameters to describe generic eigenfunctions of double elliptic…
Conformal Lagrangians from the (formal) near boundary analysis of AdS gauge fields
Alexander Chekmenev, Maxim Grigoriev
A simple generating procedure for Lagrangians of conformal gauge fields of mixed-symmetry type is presented. The construction originates from the analysis of the near-boundary beha…
Hamiltonian formalism for Bose excitations in a plasma with a non-Abelian interaction
Yu. A. Markov, M. A. Markova, N. Yu. Markov +1
We have developed the Hamiltonian theory for collective longitudinally polarized colorless excitations (plasmons) in a high-temperature gluon plasma using the general formalism for…
Difference of mutant knot invariants and their differential expansion
L. Bishler, Saswati Dhara, T. Grigoryev +6
We evaluate the differences of HOMFLY-PT invariants for pairs of mutant knots colored with representations of , which are large enough to distinguish between them. These mut…
Spinor-Helicity Formalism for Massless Fields in AdS III: Contact Four-Point Amplitudes
Balakrishnan Nagaraj, Dmitry Ponomarev
We study contact four-point amplitudes in the spinor-helicity formalism in anti-de Sitter space. We find that these amplitudes can be brought to an especially simple form, which we…
One-loop Finiteness of Chiral Higher Spin Gravity
Evgeny Skvortsov, Tung Tran
One of the main ideas behind Higher Spin Gravities is that the higher spin symmetry is expected to leave no room for counterterms, thereby eliminating UV divergences that make the…

Nadav Drukker, Simone Giombi, Arkady A. Tseytlin +1
Surface operators in the 6d (2,0) theory at large have a holographic description in terms of M2 branes probing the AdS M-theory background. The most symmetric, 1…
