Abstract:
Classical results of Shepp and Feldman give a criterion for a product measure which is a countable power of a measure on R with positive density to be equivalent to its shift by any vector in ℓ2. In this work a similar problem is studied for shifts of a measure by vectors in ℓq for 1⩽q<2.
Keywords:
space of quasi-invariance, space of equivalent shifts, Shepp's theorem, product measure.
