Hamid Reza Moradi, Mohsen Erfanian Omidvar · Journal of New Researches in Mathematics · 2017
In this paper, we introduce the notion of sesquilinear map on Β(H) . Based on this notion, we define the quadratic map, which is the generalization of positive linear map. With the help of this concept, we prove several well-known equality and inequality...
