Second order perturbation for operator functions
In this talk, we will give some recent results of non-commutative analysis. We will explain which natural objects appear in the study of operator functions, that is to say functions defined on a real interval with values in a subspace (here, the Schatten classes) of the space of operators bounded on a Hilbert space and defined using the functional calculus of these operators. In particular, we will study the continuity of such functions and their representations in the form of “measurable” Schur multipliers. We will apply these results to the resolution of a perturbation problem on Taylor remains with operator values.
