Information × Registration Number 0212U004260, 0109U002242 , R & D reports Title Vector lattice and the relationship between joint and separate properties of functions of several variables. popup.stage_title Head Matijchuk Myhaylo Ivanovych, Доктор фізико-математичних наук Registration Date 01-02-2012 Organization Yuri Fedkovych Chernivtsi National University popup.description2 A theory of narrow operators on vector lattices has been developed, and analogies of known Kalton's and Rosenthal's theorems on decompositions of operators have been obtained.The problem of constructing of functions with a given oscillation for different functional classes has been investigated, and related general methods have been developed. We have solved the Aydelhayt problem on absolutely continuous functions from the well known "Scottish Book". We have also solved the equation of string vibration in the class of separately twice differentiable functions Product Description popup.authors Волошин Галина Аркадіївна Герасимчук Василь Григорович Карлова Олена Олексіївна Косован Василь Михайлович Лінчук Юрій Степанович Маслюченко Володимир Кирилович Маслюченко Олександр Володимирович Михайлюк Володимир Васильович Нестеренко Василь Володимирович Попов Михайло Михайлович Фотій Олена Георгіївна Холоменюк Віолетта Андріївна popup.nrat_date 2020-04-02 Close
