Abstract:
The notion of the limit spectral measure of a metric triple (i.e., a metric measure space)
is defined. If the metric is square integrable, then the limit spectral measure
is deterministic and coincides with the spectrum of the integral
operator on L2(μ) with kernel ρ. An example
in which there is no deterministic spectral measure is constructed.
