On the position of the space of representable operators in the space of linear operators

Comment.Math.Univ.Carolinae 38,2 (1997) 255-262.

Abstract:We show results about the existence and the nonexistence of a projection from the space $L(L^1(\lambda ),X)$ of all linear and bounded operators from $L^1(\lambda )$ into $X$ onto the subspace $R(L^1(\lambda ),X)$ of all representable operators.

Keywords: representable operators, vector measures, L-projections, copies of $c_0$
