Mathematical Notes


In the note, it is proved that, under natural conditions, any infinite-dimensional unitary representation T of a direct product of groups G = K × N, where K is a compact group and N is a locally compact Abelian group, is imaged by a representation of the nonstandard analog \(\tilde G\) of the group G in the group of nonstandard matrices of a fixed nonstandard size.

Key words

unitary representation nonstandard matrix imaging of groups Boolean algebra Stone space Casimir operator
