Abstract

Let T = [Tij ] \in \BbbM mn(\BbbC ) be accretive-dissipative, where Tij \in \BbbM n(\BbbC ) for i, j = 1, 2, ...,m. Let f be a function that is convex and increasing on [0,\infty ) where f(0) = 0. Then \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| \bigm| f \left( \sum i
增生耗散块矩阵的范数不等式
设T=[Tij]\in\BbbMmn(\BbbC)是增生耗散的,其中对于i,j=1,2。。。,m。设f是在[0,\infty)上凸且递增的函数,其中f(0)=0。然后\bigm|\bigm|| \bigm| \bigm |\bigm || \bigm | \bigm|1\bigm|3\bigm(\sum i
