  Dynamical linked cluster expansions are linked cluster expansions with
hopping parameter terms endowed with their own dynamics. This amounts to a
generalization from 2-point to point-link-point interactions. An associated
graph theory with a generalized notion of connectivity is reviewed. We discuss
physical applications to disordered systems, in particular to spin glasses,
such as the bond-diluted Ising model and the Sherrington-Kirkpatrick spin
glass. We derive the rules and identify the full set of graphs that contribute
to the series in the quenched case. This way it becomes possible to avoid the
vague extrapolation from positive integer n to n=0, that usually goes along
with an application of the replica trick.
