The quantum group, Harper equation and the structure of Bloch eigenstates on a honeycomb lattice
The tight-binding model of quantum particles on a honeycomb lattice is investigated in the presence of homogeneous magnetic field. Provided the magnetic flux per unit hexagon is rational of the elementary flux, the one-particle Hamiltonian is expressed ...

The article shows that the system of the functional equations$S(x+y)=S(x)C(y)+S(y)C(x),,C(x+y)=C(x)C(y)-S(y)S(x)$ defines abroader class of the functions than the trigonometric equations.

Steady heat conduction of material with coated inclusion in the case of imperfect contact
We discuss a potential steady heat conduction for composites with the coated cylindrical inclusion under an imperfect contact condition. We rewrite equivalently the considered problem to a conjugation problem for analytic functions which is reduced then ...

We pursue our study of the antiperiodic dynamical 6-vertex model using Sklyanin's separation of variables approach, allowing in the model new possible global shifts of the dynamical parameter.

A System of Schrödinger’s Problems and Functional Equations
We propose and study a system of Schrödinger's problems and functional equations in probability theory. More precisely, we consider a system of variational problems of relative entropies for probability measures on a Euclidean space with given two endpoint marginals, which can be defined inductively.

Tensor analysis and an orthogonal curvilinear coordinate system have been used to derive a complete set of equations for piezo-magneto-elastic analysis of a functionally graded (FG) thick shell of revolution with variable thickness and curvature.

Existence Theorem for Integral and Functional Integral Equations with Discontinuous Kernels
Existence of extremal solutions of nonlinear discontinuous integral equations of Volterra type is proved. This result is extended herein to functional Volterra integral equations (FVIEs) and to a system of discontinuous VIEs as well.

QQ-system and non-linear integral equations for scattering amplitudes at strong coupling
We provide the two fundamental sets of functional relations which describe the strong coupling limit in AdS 3 of scattering amplitudes in N $$ \mathcal{N} $$ = 4 SYM dual to Wilson loops (possibly extended by a non-zero twist l): the basic QQ-system and ...
