Homogenization in the energy variable for a neutron transport model
Harsha Hutridurga, Olga Mula, Francesco Salvarani
This article addresses the homogenization of linear Boltzmann equation when the optical parameters are highly heterogeneous in the energy variable. We employ the method of two-scal…
On near-cloaking for linear elasticity
Richard Craster, Andre Diatta, Sebastien Guenneau +1
We make precise some results on the cloaking of displacement fields in linear elasticity. In the spirit of transformation media theory, the transformed governing equations in Cosse…
Existence and uniqueness analysis of a non-isothermal cross-diffusion system of Maxwell-Stefan type
Harsha Hutridurga, Francesco Salvarani
In this article we prove local-in-time existence and uniqueness of solution to a non-isothermal cross-diffusion system with Maxwell-Stefan structure.
Maxwell-Stefan diffusion asymptotic for gas mixtures in non-isothermal setting
Harsha Hutridurga, Francesco Salvarani
A mathematical model is proposed where the classical Maxwell-Stefan diffusion model for gas mixtures is coupled to an advection-type equation for the temperature of the physical sy…
Cloaking via mapping for the heat equation
Richard Craster, Sebastien Guenneau, Harsha Hutridurga +1
This paper explores the concept of near-cloaking in the context of time-dependent heat propagation. We show that after the lapse of a certain threshold time instance, the boundary…
Heterogeneity and strong competition in ecology
Harsha Hutridurga, Chandrasekhar Venkataraman
We study a competition-diffusion model while performing simultaneous homogenization and strong competition limits. The limit problem is shown to be a Stefan type evolution equation…
