Web9 iul. 2024 · In fact, we can represent the solution to the general nonhomogeneous heat equation as the sum of two solutions that solve different problems. First, we let v(x, t) … In the mathematical study of heat conduction and diffusion, a heat kernel is the fundamental solution to the heat equation on a specified domain with appropriate boundary conditions. It is also one of the main tools in the study of the spectrum of the Laplace operator, and is thus of some auxiliary importance throughout mathematical physics. The heat kernel represents the evolution of temperature in a region whose boundary is held fixed at a particular temperature (typically zero), …
