Fundamental Solution of Elliptic Equation with Positive Definite Matrix Coefficient

Cauchy: Jurnal Matematika Murni dan Aplikasi, 2018
In this paper, we study the fundamental solution of elliptic equations with real constant coefficients   where is a positive definite matrix. We obtained by searching the radial solution so that we solved the equation into ordinary differential equations.

Necessary and sufficient conditions on the existence of solutions for the exterior Dirichlet problem of Hessian equations

Boundary Value Problems, 2022
In this paper, we consider the exterior Dirichlet problem of Hessian equations σ k ( λ ( D 2 u ) ) = g ( x ) $\sigma _{k}(\lambda (D^{2}u))=g(x)$ with g being a perturbation of a general positive function at infinity. By estimating the eigenvalues of the

Non-Fourier Heat Transfer with Phonons and Electrons in a Circular Thin Layer Surrounding a Hot Nanodevice

Entropy, 2015
A nonlocal model for heat transfer with phonons and electrons is applied to infer the steady-state radial temperature profile in a circular layer surrounding an inner hot component. Such a profile, following by the numerical solution of the heat equation,
