✦ Synopsis

It is pointed out that first-and second-order dynamic susceptibilities for one observable can be expressed by a matrix resolvent in Liouville space~ In this way projection operator formalism is possible. The simplest choice of a projector is discussed, leading to generalized memory functions for the second-order susceptibility.
