Query: Sharp Estimates for Norms of Functions from Conjugate Classes in Metrics
  C and L   Sharp estimates for C - and L - norms of functions that are conjugate with
functions from the classes W^rH_\omega of periodic functions having prescribed
concave majorant of moduli of continuity, as well as sharp estimates for the
differences of such functions are obtained.
