I would like to define a shift operator similar to the derivative for continuous time that is already built into Mma. i.e. Shift[ how far ][ expression head ] [ variable(s) to which shift should be applied ] I would also like to have it enjoy a relationship to something called S sort of like D[] and Derivative[][][]. Any ideas on how to define it or where I could go to learn how to do it right? I have the standard Mma reference book by Wolfram but haven't (as of yet) been able to extract the proper way to get what I need. Thanks in Advance, Todd Pitts
