Two properties of sequence of vector measures on effect algebras

Let (L, circle plus, 0, 1) be an effect algebra and let X be a Banach space. A function mu : L -> X is called a vector measure if mu(a circle plus b) = mu(a) + mu(b) whenever a perpendicular to b in L. The function mu is said to be s-bounded if lim(n ->infinity) mu(a(n)) = 0 in X for any orthogonal sequence (a(n))(n is an element of N) in L. In this paper, we introduce two properties of sequence of s-bounded vector measures and give some results on these properties.
