Operator Cebirleri ve Tamamen Pozitif Operatorler

In this thesis we survey positive and completely positive maps defined onoperator systems. In Chapter 3 we study the properties of positive maps as wellas construction of positive maps under certain conditions. In Chapter 4 we focuson completely positive maps. We give some conditions on domain and rangeunder which positivity implies complete positivity. The last chapter consists ofStinespring?s dilation theorem and its applications to various areas.1
