Abstract: In this paper, we aim to show that the Meijer $G$-functions can serve to find explicit solutions of partial differential equations (PDEs) related to some mathematical models of physical phenomena, as for example, the Laplace equation, the diffusion equation and the Schr$\ddot{o}$dinger equation. Usually, the first step in solving such equations is to use the separation of variables method to reduce them to ordinary differential equations (ODEs). Very often this equation happens to be a case of the linear ordinary differential equation satisfied by the $G$-function, and so, by proper selection of its orders $m; n; p; q$ and the parameters, we can find the solution of the ODE explicitly. We illustrate this approach by proposing solutions as: the potential function $\Phi$, the temperature function $T$ and the wave function $\Psi$, all of which are symmetric product forms of the Meijer $G$-functions. We show that one of the three basic univalent Meijer $G$-functions, namely $G^{1,0}_{0,2},$ appears in all the mentioned solutions.

Key words and phrases: Meijer $G$-functions; partial differential equations; Laplace equation; diffusion equation; Schrödinger equation; separation of variables.
