In this paper, we define the almost uniform convergence and the almost everywhere convergence for cone-valued functions with respect to an operator valued measure. We prove the Egoroff theorem forP-valued functions and operator valued measure q: ®L (P, Q), where R is a s-ring of subsets of X¹q, (P, V) is a quasi-full locally convex cone and (Q, W) is a locally convex complete lattice cone.
