Abstract

Using the group G(1)G(1) of invertible elements and the maximal ideals mx\mathfrak{m}_x of the commutative algebra C(X)C(X) of real-valued functions on a compact regular space XX, we define a Borel action of the algebra on the measure space (X,μ)(X,\mu) with μ\mu a Radon measure. The zero sets Z(X)Z(X) of the algebra C(X)C(X) is used to study the ergodicity of the G(1)G(1)-action via its action on the maximal ideals mx\mathfrak{m}_x which defines an action groupoid G=mxG(1)\mathcal{G} = \mathfrak{m}_x \ltimes G(1) trivialized on XX. The resulting measure groupoid (G,C)(\mathcal{G},\mathcal{C}) is used to define a proper action on the generalized space M(X)\mathcal{M}(X). The existence of slice at each point of M(X)\mathcal{M}(X) present it as a cohomogeneity-one G\mathcal{G}-space. The dynamical system of the algebra C(X)C(X) is defined by the action of the measure groupoid (G,C)×M(X)M(X)(\mathcal{G},\mathcal{C}) \times \mathcal{M}(X) \to \mathcal{M}(X).
