Yes... I find the infinite case difficult to reason about: With a finite grid, we can reasonably ignore transient effects. But with an infinite grid, the transient effects become infinite so ignoring them seems unreasonable. Which is why I was looking for treatments of finite cases. Anyways, I've a lot to think about now (thanks Aai!). -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
