Query: On the existence of a torsor structure for Galois covers over a complete
  discrete valuation ring   In this note we investigate the problem of existence of a torsor structure
for Galois covers of (formal) schemes over a complete discrete valuation ring
of residue characteristic $p>0$ in the case of abelian Galois groups of type
(p,p,...,p).
