"Uniqueness of Dirichlet forms associated with systems of infinitely many Brownian balls in R^d",
Probab. Theory Related Field 109(1997), no.2, pp.275-299.
Dirichlet forms associated with systems of infinitely many Brownian
balls in R^d are studied. Introducing a linear operator L_0 defined
on a space of smooth local functions, we show the uniqueness of Dirichlet
forms associated with self adjoint Markovian extensions of L_0.
We also discuss the ergodicity of the reversible process associated with
the Dirichlet form.
