This book deals mainly with modelling systems that change with time. The evolution equations that it describes can be found in a number of application areas, such as kinetics, fragmentation theory and mathematical biology. This will be the first self-contained account of the area.

We consider perturbations of dynamical semigroups on the algebra of all bounded operators in a hilbert space generated by covariant completely positive measures on the semi-axis.
