Representations of holonomy algebras and shadow states
It has been argued that the Ashtekar-Lewandowski
representation of the
Ashtekar-Isham holonomy algebra is fundamental, in the sense that any
other
representation can be obtained by a suitable limit procedure.
We propose to clarify that statement, providing, in particular, a
canonical way
of mapping GNS states to a family of vectors of the Ashtekar-Lewandowski
Hilbert space. The so-called family of
shadow states thus obtained
converges,
as states of the algebra, to the original GNS state.
