Direct Problem for Gas Diffusion in Polar Firn with Variable Coefficients

Sophie Moufawad, Nabil Nassif, Faouzi Triki

We consider the mathematical model of gas trapping in deep polar ice (firns), which consists of a parabolic partial differential equation, that can degenerate at one boundary extre…

Estimates on the stability constant for the truncated Fourier transform

Mirza KaramehmedoviÄ, Martin SÃ¦bye CarÃ¸e, Faouzi Triki

In this paper we are interested in the inverse problem of recovering a compact supported function from its truncated Fourier transform. We derive new Lipschitz stability estimates…

Recovering the Polytropic Exponent in the Porous Medium Equation: Asymptotic Approach

Hagop Karakazian, Toni Sayah, Faouzi Triki

In this paper we consider the time dependent Porous Medium Equation, $u_{t} = I^ u^{3}$ with real polytropic exponent $I^^{3} > 1$ , subject to a homogeneous Dirichlet boundary condition. We…
