Query: On boundary and global behavior of mappings with branching on Riemannian
  surfaces   In the present paper, we investigate non-homeomorphic mappings of Riemannian
surfaces of Sobolev class. We have obtained some estimates of distortion of
moduli of families of curves. As consequence, we have obtained results about
the boundary behavior of such mappings between domains on Riemannian surfaces.
