О топологической устойчивости непрерывных функций в некоторых пространствах, связанных с рядами Фурье

We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions  have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
