Abstract

In this article, we introduce the notion of pp-(DPL)(DPL) sets.\ Also, a factorization result for differentiable mappings through Dunford-Pettis pp-convergent operators is investigated.\ Namely, if X,Y X ,Y are real Banach spaces and UU is an open convex subset of X,X, then we obtain that, given a differentiable mapping f:UYf: U\rightarrow Y its derivative ff^{\prime} takes UU-bounded sets into pp-(DPL)(DPL) sets if and only if it happens f=gS,f=g\circ S, where SS is a Dunford-Pettis pp-convergent operator from XX into a suitable Banach space ZZ and g:S(U)Yg:S(U)\rightarrow Y is a G\^ateaux differentiable mapping with some additional properties.
