13. Two-Dimensional Laplace Equation
The two-dimensional Laplace equation is a critical second-order partial differential equation reflecting steady-state phenomena across various fields such as physics and engineering. Central to the equation are its properties, boundary value problems, and methods for solution, particularly through the separation of variables. Analytical techniques prevail, while numerical methods provide alternatives for complex geometries and scenarios where analytical solutions are intractable.
