Query: Diagonality of actions and KMS weights   The paper contains a description of a connection between diagonal actions and
certain KMS weights on groupoid $C^{*}$-algebras. It furthermore contains the
realization of a graph $C^{*}$-algebra of a countable graph as the groupoid
$C^{*}$-algebra of a local homeomorphism and applies the theory obtained on
these algebras.
