Pseudo-differential operators (PDOs) are a class of operators that generalize differential operators. They play a crucial role in the analysis of partial differential equations (PDEs), especially in the study of solutions and their regularity properties. PDOs are particularly useful in the context of Fourier analysis and microlocal analysis. ### Definition A pseudo-differential operator is typically defined in terms of its action on test functions through a symbolic calculus.
