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.
The Jacobi zeta function is a complex function that arises in the context of elliptic functions, named after the mathematician Carl Gustav Jacob Jacobi. It is often denoted as \( Z(u, m) \), where \( u \) is a complex variable and \( m \) is a parameter related to the elliptic modulus. The Jacobi zeta function is defined in relation to the elliptic sine and elliptic cosine functions.
Jacobi elliptic functions are a set of basic elliptic functions that generalize trigonometric functions and are used in many areas of mathematics, including number theory, algebraic geometry, and physics. They are particularly useful in the study of elliptic curves and in solving problems involving periodic phenomena. The Jacobi elliptic functions are defined in terms of a parameter, typically denoted as \(k\) (or \(m\)), which is called the elliptic modulus.
