Good measures on locally compact Cantor sets
Abstract
We study the set M(X) of full non-atomic Borel (finite or infinite) measures on a non-compact locally compact Cantor set X. For an infinite measure in M(X), the set is called defective. We call non-defective if . The class consists of probability measures and infinite non-defective measures. We classify measures from with respect to a homeomorphism. The notions of goodness and compact open values set are defined. A criterion when two good measures from are homeomorphic is given. For any group-like we find a good probability measure on X such that . For any group-like and any locally compact, zero-dimensional, metric space A we find a good non-defective measure on X such that and is homeomorphic to A. We consider compactifications cX of X and give a criterion when a good measure can be extended to a good measure on cX.
