摘要
In this note we show that the representation of the additive group of the Hilbert space L(2)([0, 1], R) on L(2)([0, 1], C) given by the multiplication operators pi(f) := e(if) is continuous but its space of smooth vectors is trivial. This example shows that a continuous unitary representation of an infinite dimensional Lie group need not be smooth.
