Indiscernible pairs of countable sets of reals at a given projective level
Vladimir Kanovei, Vassily Lyubetsky
Using an invariant modification of Jensen's "minimal singleton" forcing, we define a model of ZFC, in which, for a given , there exists a lightface …
Recursive enumerability and elementary frame definability in predicate modal logic
Mikhail Rybakov, Dmitry Shkatov
We investigate the relationship between recursive enumerability and elementary frame definability in first-order predicate modal logic. On the one hand, it is well-known that every…
Dynamics of non-Abelian strings in the theory interpolating from to supersymmetric QCD
A. Gorsky, E. Ievlev, A. Yung
We study the dynamics of non-Abelian vortex strings supported in supersymmetric QCD with the U gauge group and quark flavors deformed by the mass …
Flavored extended instanton in QCD
Alexander Gorsky, Andrey Grekov
In this paper we discuss new flavored space-like defects in confined QCD which can be considered as the Euclidean extended instantons carrying the topologically quantized currents.…
Complete solution to Gaussian tensor model and its integrable properties
H. Itoyama, A. Mironov, A. Morozov
Similarly to the complex matrix model, the rainbow tensor models are superintegrable in the sense that arbitrary Gaussian correlators are explicitly expressed through the Clebsh-Go…
Spectrum of the reflection operators in different integrable structures
Gleb A. Kotousov, Sergei L. Lukyanov
The reflection operators are the simplest examples of the non-local integrals of motion, which appear in many interesting problems in integrable CFT. For the so-called Fateev, quan…
