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.
