evidence: In mathematics , Stone 's theorem on one-parameter unitary groups is a basic theorem of functional analysis that establishes a one-to-one correspondence between self-adjoint operators on a Hilbert space and one-parameter families. mathematics. mathematics. one-parameter. one-parameter group. functional analysis. functional analysis.

Such one-parameter families are ordinarily referred to as strongly continuous one-parameter unitary groups .. one-parameter. one-parameter group. strongly continuous. strong operator topology. The theorem was proved by , and showed that the requirement that be strongly continuous can be relaxed to say that it is merely weakly measurable , at least when the Hilbert space is separable ..

This is a very stunning theorem , as it allows to define the derivative of the mapping , which is only supposed to be continuous .. It is also related to the theory of Lie groups and Lie algebras ..
