Abstract:
We consider two unitary representations of the infinite-dimensional groups of smooth paths with values in a compact Lie group. The first representation is induced by quasi-invariance of the Wiener measure, and the second representation is the energy representation. We define these representations and their basic properties, and then we prove that these representations are unitarily equivalent.
Key words and phrases:
quasi-invariance, stochastic differential equations, Lie groups, representations of infinite-dimensional groups.
