Completely semi-$\varphi$-maps
  We introduce completely semi-$\varphi$-maps on Hilbert $C^*$-modules as a generalization of $\varphi$-maps. This class of maps provides examples of CP-extendable maps which are not CP-H-extendable, in Skeide-Sumesh's sense. Using the CP-extendability of completely semi-$\varphi$-maps, we give a representation theorem, similar to Stinespring's representation theorem, for this class of maps which can be considered as strengthened and generalized form of Asadi's and Bhat-Ramesh-Sumesh's analogues of Stinespring representation theorem for $\varphi$-maps.   We also define an order relation on the set of all completely semi-$\varphi$-maps and establish a Radon-Nikodym type theorem for this class of maps in terms of their representations.
