Abstract

Introduction. The local rings, A, of the totle are complete, neotherian, local rings of dimension 0, [3, Th. 2] proved useful in the theory of cohomological dimension. By characterizing the etale sheaves (see ? 1) over a special local ring (Th. 1), we are able to further generalize these structure theorems to obtain the canonical decomposition of a sheaf over such a ring into infinitesimal and etale parts, (Th. 2). Hopefully, our structure theorem will help in the investigation of cohomological phenomena over special local rings.
