  A model for the fragmentation of a nucleus is developed. Parallels of the
description of this process with other areas are shown which include Feynman's
theory of the $\lambda$ transition in liquid Helium, Bose condensation, and
Markov process models used in stochastic networks and polymer physics. These
parallels are used to generalize and further develop a previous exactly
solvable model of nuclear fragmentation. An analysis of some experimental data
is given.
