We also show application of maximum principle in showing uniqueness and stability of solution of heat equation. Finally, we also apply it in finding optimum utility function under a given budget constraint in Microeconomics.enHarmonic FunctionsApplication to MicroeconomicsDiscretization of Dirichlet ProblemThesis
