Wielandt theorem

In mathematics, the Wielandt theorem characterizes the gamma function, defined for all complex numbers for which by as the only function defined on the half-plane such that: * is holomorphic on ; * ; * for all and * is bounded on the strip . This theorem named after the mathematician Helmut Wielandt.
