Secular evolution of resonant dynamical systems is one of the most
difficult problems in celestial mechanics. However, it can be efficiently
cured via the introduction of the so-called pendulum model. In this talk
I will review the background of this theory and introduce an alternative
solution that may suit better to some numerical applications.
