 Kontorovich–Lebedev transform

The Kontorovich–Lebedev transform is an integral transform used in mathematics and physics to solve certain types of problems, particularly in the context of integral equations and the theory of special functions. It is named after the mathematicians M. G. Kontorovich and N. N. Lebedev, who developed this transform in the context of mathematical analysis. The transform can be used to relate functions in one domain to functions in another domain, much like the Fourier transform or the Laplace transform.
