We study the nonlinear dynamics of globally coupled nonidentical oscillators in the framework of two order parameter (mean field and amplitude-frequency correlator) reduction. The main result of the paper is the exact solution of a corresponding nonl

In this work we study the existence of solitary waves in nonlinear equations of Schrodinger type. We prove the existence of the positive solution and using the bifurcation theory show that the norm of the given solution tends to zero as the coefficie

We study the homogenization of a variational problem corresponding to a class of nonlinear elliptic equations with nonstandard growth in a domain with a connected inclusion like a net of infinitely high conductivity. The variational problem is studie

We study the asymptotic behavior, as e→0, of ue solutions to a nonlinear elliptic equation with nonstandard growth condition in domains containing a grid-type microstructure Fe that is concentrated in an arbitrary small neighborhood of a given hype

In this work we consider a model problem describing one phase flow through a thin porous layer made of weakly per- meable porous blocks separated by thin fissures. The flow is modeled by a linear parabolic equation considered in a bounded 2D domain w

Using theoretical arguments, we prove the numerically well-known fact that the eigenvalues of all localized stationary solutions of the cubic-quintic $(2+1)$-dimensional nonlinear Schr\"odinger equation exhibit an upper cutoff value. The existence of

We describe the collapse of the bosonic component in a boson-fermion mixture due to the pressure exerted on them by a large fermionic component, leading to collapse in a system with all-repulsive interactions. We describe the phenomena early collapse

In this paper we study blow-up phenomena in general coupled nonlinear Schrodinger equations with different dispersion coefficients. We find sufficient conditions for blow-up and for the existence of global solutions. We discuss several applications o
