Network Approximation in the Limit of¶Small Interparticle Distance of the¶Effective Properties of a High-Contrast¶Random Dispersed Composite

- L. Berlyand, A. Kolpakov
- Mathematics
- 1 September 2001

Abstract We consider a high-contrast two-phase composite such as a ceramic/polymer composite or a fiberglass composite. Our objective is to determine the dependence of the effective conductivity (or… Expand

Generalized Clausius–Mossotti Formula for Random Composite with Circular Fibers

- L. Berlyand, V. Mityushev
- Mathematics
- 2001

An important area of materials science is the study of effective dielectric, thermal and electrical properties of two phase composite materials with very different properties of the constituents. The… Expand

Large time asymptotics of solutions to a model combustion system with critical nonlinearity

- L. Berlyand, J. Xin
- Mathematics
- 1 March 1995

We consider a model semilinear reaction-diffusion system with cubic nonlinear reaction terms and small spatially decaying initial data on R1. The model system is motivated by the thermal-diffusive… Expand

Polyharmonic homogenization, rough polyharmonic splines and sparse super-localization

- H. Owhadi, L. Zhang, L. Berlyand
- Mathematics
- 4 December 2012

We introduce a new variational method for the numerical homogenization of divergence form elliptic, parabolic and hyperbolic equations with arbitrary rough (L^∞) coefficients. Our method does not… Expand

Increase and Decrease of the Effective Conductivity of Two Phase Composites due to Polydispersity

- L. Berlyand, V. Mityushev
- Materials Science
- 1 February 2005

We present a two-dimensional mathematical model of a composite material with conducting inclusions (fibers) embedded in a matrix. Our main objective is to study how polydispersity (two different… Expand

On uniqueness of vector-valued minimizers of the Ginzburg-Landau functional in annular domains

- D. Golovaty, L. Berlyand
- Mathematics
- 1 March 2002

Abstract. Consider a class of Sobolev functions satisfying a prescribed degree condition on the boundary of a planar annular domain. It is shown that, within this class, the Ginzburg-Landau… Expand
