Mixed percolation as a bridge between site and bond percolation
(183K, postscript)

ABSTRACT.  By using mixed percolation as a bridge between site and 
bond percolation, we derive a new inequality between the 
critical points of these processes, which is optimal in a 
certain sense, and we also extend a result on the crossover 
exponent of bond diluted Potts models to site diluted 
Potts models. Some new results about the critical line in 
mixed percolation are also proved.
