Reductions of the universal hierarchy and rdDym equations and their symmetry properties

P. Holba, I. S. Krasil'shchik, O. I. Morozov +1

We consider the equations $u_{y y} = u_{y} u_{xx} - (u_{x} + u) u_{x y} + u_{x} u_{y}$ and $u_{y y} = (u_{x} + x) u_{x y} - (u_{xx} + 2) u_{y}$ that arise as reductions of the universal hierarchy and…

Mode matching methods for spectral and scattering problems

A. Delitsyn, D. S. Grebenkov

We present several applications of mode matching methods in spectral and scattering problems. First, we consider the eigenvalue problem for the Dirichlet Laplacian in a finite cyli…

Cluster integrable systems, q-Painleve equations and their quantization

M. Bershtein, P. Gavrylenko, A. Marshakov

We discuss the relation between the cluster integrable systems and $q$ -difference Painlevé equations. The Newton polygons corresponding to these integrable systems are all 16 conve…

On Gradings Modulo 2 of Simple Lie Algebras in Characteristic 2

Andrey Krutov, Alexei Lebedev

The ground field in the text is of characteristic 2. The classification of modulo 2 gradings of simple Lie algebras is vital for the classification of simple finite-dimensional Lie…

Twist-field representations of W-algebras, exact conformal blocks and character identities

M. Bershtein, P. Gavrylenko, A. Marshakov

We study the twist-field representations of W-algebras and generalize construction of the corresponding vertex operators to D- and B-series. It is shown, how the computation of cha…

The Resultant of Developed Systems of Laurent Polynomials

Askold Khovanskii, Leonid Monin

Let $R_{Δ} (f_{1}, \dots, f_{n + 1})$ be the {\it $Δ$ -resultant} (see below) of $(n + 1)$ -tuple of Laurent polynomials. We provide an algorithm for computing $R_{Δ}$ assuming that an $n$ -tuple…

Hardness of almost embedding simplicial complexes in $R^{d}$

Arkadiy Skopenkov, Martin Tancer

A map $f : K \to R^{d}$ of a simplicial complex is an almost embedding if $f (σ) \cap f (τ) = \emptyset$ whenever $σ, τ$ are disjoint simplices of $K$ . Theorem. Fix integers $d,…

Cheap Complex Limit Cycles

Nataliya Goncharuk, Yury Kudryashov

Consider a holomorphic foliation with singularities of a 2-dimensional complex manifold. In this article we prove a new sufficient condition for this foliation to have countably ma…
