In this paper,we introduce rough sets into linear space.First,we put forward the concepts of upper and lower approximations of a subset in a linear space.Then,we give the definitions of upper and lower rough linear subspaces and upper and lower rough A-subspaces of a linear space.At last,we study their properties and give a series of meaningful results.
