On the support of the product of resolutions of identity (English)
0 references
It is known that the support of the joint resolution of identity of an uncountable family of commuting normal operators can be empty. The author gives a general construction which covers the known examples and allows to produce new ones. In the second part of the paper the properness of the support is proved for some families of operators which depend continuously on an indexing parameter.
