Query: Nonlocal problem with conjugation conditions for a degenerate higher
  order equations with the Caputo fractional derivative   In this paper, for a degenerate higher order equation with a fractional
derivative in the sense of Caputo, a nonlocal problem with conjugation
conditions in a rectangular domain is studied. The solution is constructed in
the form of a Fourier series in the eigenfunctions of a one-dimensional
problem. A criterion for the uniqueness of a solution is given.
