Abstract
We check here numerically and establish the validity of a simple estim ate for the polymer theta-point on various pure and diluted lattices. Our study on two-dimensional lattices supports a linear relationship o f the theta-point value with the average number Z(eff) of non-bonded ( nearest) neighbours on a random self-avoiding walk (SAW). This Z(eff) in turn can be estimated from the connectivity constant mu of SAWs of the corresponding lattice.
