On bistochastic Kadison-Schwarz operators onM2(ℂ)
In this paper we describe bistochastic Kadison-Schawrz operators acting on M2(C). Such a description allows us to �nd positive, but not Kadison-Schwarz operators. Moreover, by means of that characterization we are able to construct Kadison-Schawrz operators, which are not completely positive.
