Research interests of Arkady Tseytlin include quantum field theory and quantum gravity, superstring theory, conformal theories and AdS/CFT correspondence. He obtained several key results in superstring theory and field theory. In particular, he developed the sigma model approach to string theory, discovered the fundamental role of BornInfeld action as the open string effective action, developed the method of constructing composite solitonic solutions in supergravity describing supersymmetric bound states of branes, contributed to investigations of Dbranes that led to AdS/CFT duality, constructed the action of superstings in AdS5 x S5 space and made substantial contributions to the integrabilitybased approach to gaugestring duality.

Scientific interests of Maxim Grigoriev involve mathematical foundations of gauge systems (constrained dynamics and symmetries, BatalinVilkovisky quantization) higherspin gauge theories and holography, superstring sigma models and noncommutative theories. He proposed the socalled parent formulation of general gauge theories which systematically unifies BatalinVilkovisky and Hamiltonian BRST approaches into a unique formalism which has the structure of (generalized) AlexandrovKontsevichSchwartzZaboronsky (AKSZ) sigmamodel, which is especially useful in the context of diffeomorphisminvariant theories and higher spin holography.

Dr. Levkov is a research fellow of ITMP and Institute for Nuclear Research RAS. His scientific interests are shared between cosmology of ultralight dark matter, black hole physics, instantons and semiclassical description of nonperturbative transitions in quantum field theory. He and his collaborators for the first time computed the probability of baryon number violation in electroweak particle collisions at colliders, were first to describe kinetic BoseEinstein condensation of light dark matter due to gravitational interactions.

The main focus of Konstantin’s research is the AdS/CFT correspondence for QFTs with higher symmetries such as 2d CFT and HS gravity. He and collaborators pioneered studies of the framelike formulation for general free and interacting massless AdS fields, built mixedsymmetry conserved currents along with their duals, proposed higherspin extensions of the JackiwTeitelboim gravity. More recent results include the combinatorial representation for minimal CFT with W symmetry, the semiclassical AdS/CFT correspondence between higherpoint conformal blocks and geodesic trees, largeс torus CFT blocks and their duals.

Scientific interests of Sergey Mironov involve the mathematical aspects of modern cosmology and gravity, including theories with higher derivatives, the AGT conjecture between gauge and conformal theories, topological field theories, especially knot theory, as well
as their connection with integrable systems. In collaboration with his collegues he derived a number of formulas for universal parts of the triple functions for the W algebra. Another important result is the discovery of nogo theorems for stable classical solutions in theories of gravity with scalar fields of quite general form.
