%0 Journal Article %T The Nemytskii operator on bounded p-variation in the mean spaces %A Ren¨¦ Erl¨ªn Castillo %J Matem¨¢ticas : Ense£¿anza Universitaria %D 2011 %I Universidad del Valle %X We introduce the notion of bounded p-variation in the sense of Lp-norm. We obtain a Riesz type result for functions of bounded p-variation in the mean. We show that if the Nemytskii operator map the bounded p-variation in the mean spaces into itself and satisfy some Lipschitz condition there exist two functions g and h belonging to the bounded p-variation in the mean space such that f(t, y) = g(t)y + h(t), t 2 [0, 2pi], y 2 R. %U http://www.redalyc.org/articulo.oa?id=46818606003
