Abstract:
Tree polymers are simplifications of
1+1 dimensional lattice polymers made up
of polygonal paths of a (nonrecombining)
binary tree having random path probabilities.
As in the case of lattice polymers, the path
probabilities are (normalized) products of i.i.d.
positive random weights. The a.s. probability laws
of these paths are of interest under weak and strong
types of disorder. The case of no disorder provides a
benchmark since the polymers are simple symmetric
random walk paths where all of the probability laws
are known. We will discuss some recent results,
speculation and conjectures for this class of models.
This is based on joint work with Stan Williams.
