Sobolev Homeomorphisms and Composition Operators

Abstract: We study invertibility of bounded composition operators of Sobolev spaces. The problem is closely connected with the theory of mappings of finite distortion. If a homeomorphism ϕ of Euclidean domains D and D ′ generates by the composition rule ϕ * f = f • ϕ a bounded composition operator of Sobolev spaces ϕ * :, p > n − 1, has finite distortion and Luzin N -property then its inverse ϕ −1 generates the bounded composition operator from

“…Если в предложении 5 отображение ϕ : Ω → Ω ′ -гомеомор-физм, то получается утверждение, аналогичное сформулированному в работах [59], [60]. Приводимое ниже доказательство достаточности отличается от дан-ного в [59], [60] возможностью обобщить его на отображения классов Соболева со значениями в метрическом пространстве [61]. Отметим, что оценки на норму ∥Dϕ( · ) | L q (Ω)∥ в этих работах не установлены.…”

“…В работах [59], [60] утверждение теоремы 6 в случае p = ∞, q n − 1 доказано при более сильном предположении: вместо условия 2 тео-ремы 6 авторы работ [59], [60] требуют, чтобы гомеоморфизм ϕ имел конечное искажение и обладал N -свойством Лузина.…”
