Computational Physics Lectures: Partial differential equations
Important systems of linear partial differential equations are the famous Maxwell equations $$ \frac{\partial \mathbf{E}}{\partial t} = \mathrm{curl}\mathbf{B}, $$ and $$ -\mathrm{curl} \mathbf{E} = \mathbf{B} $$ and $$ \mathrm{div} \mathbf{E} = \mathrm{div}\mathbf{B} = 0. $$

This chapter provides an introduction to partial differential equations. It describes how the simplest partial differential equations arise and additionally provides ample examples. The chapter gives the definition of the Laplace operator. It also gives the expression of the field action approach.
This course aims to make students aware of the physical origins of the main partial differential equations of classical mathematical physics, including the fundamental equations of fluid and solid mechanics, thermodynamics, and classical electrodynamics.
Partial differential equation - Wikipedia
In mathematics, a partial differential equation (PDE) is an equation which involves a multivariable function and one or more of its partial derivatives. The function is often thought of as an "unknown" that solves the equation, similar to how x is thought of as an unknown number solving, e.g., an algebraic equation like x2 − 3x + 2 = 0.
Partial Differential Equations of Mathematical Physics
If an unknown function of several variables and its partial derivatives are combined in an equation, the latter is called a partial differential equation (PDE). Several times above we have come across such PDEs when dealing with functions of several variables.
Partial Differential Equations of Mathematical Physics
Partial Differential Equations of Mathematical Physics emphasizes the study of second-order partial differential equations of mathematical physics, which is deemed as the foundation of investigations into waves, heat conduction, hydrodynamics, and other physical problems.
Partial differential equations are fundamental in many important physical and mechanical disciplines. Although the names of these equations are well known, and they have been the focus of a considerable amount of research, gaining a comprehensive and deep understanding of the related physical and mechanical background is not an easy task.

In physics, PDEs describe continua such as fluids, elastic solids, temperature and concentration distributions, electromag-netic fields, and quantum-mechanical probabilities. Below we review these equations. This is the continuity equation in the differential form.
