It is known that the boundedness of the composition operator on Lebesgue spaces is equivalent to the integrability of the volume derivative of the measurable mapping inducing …

Given two metric measure spaces $ X $ and $ Y $. Let $ f: X\to Y $ be a measurable mapping and $ A\subset X $. The Banach indicatrix (multiplicity function) is defined as $ N …
We study mappings inducing a bounded composition operator on weighted Sobolev spaces on Carnot groups. An analytical description of these mappings is given in terms of …

The notion of decomposable operators acting between distinct L p-direct integrals of Banach spaces is introduced. We show that these operators generalize the composition operator in …
