Abstract: 

I am going to consider the problem of differentiability (the existence of higher derivatives) of the map A to f(A), where A is an operator and f is a function.

I will deal with the cases of self-adjoint operators, unitary operators, and contractions on a Hilbert space. The main tool is the theory of double (and multiple) operator integrals.
