Improved Upper Bounds for the Critical Probability of Oriented Percolation in Two Dimensions

We refine the method of our previous paper [2] which gave upper bounds for the critical probability in two‐dimensional oriented percolation. We use our refinement to show that \documentclass{article}\pagestyle{empty}\begin{document}$$p_c \, < \,0.6735.$$\end{document} © 1994 John Wiley & Sons, Inc.
