Query: On certain generalizations of one function and related problems (Systems
  of functional equations and generalizations of certain functions)   The present article is devoted to the generalized Salem functions, the
generailed shift operator, and certain related problems. A description of
further investigations of the author of this article is given.These
investigations (in terms of various representations of real numbers) include
the generalized Salem functions and generalizations of the Gauss-Kuzmin
problem.
