I'm trying to migrate to Sage from Maple and facing some difficulties with symbolic manipulations, which is the most important part of my work. For example, I want to define the following equality:
N(t + delta * t, A) = ( N(t, A + sigma * sqrt(delta * t)) * (1 - p(t, A))
+ N(t, A - sigma * sqrt(delta * t)) * p(t, A) )
where the function N(t,A) is yet unknown, and I can't find a way to to do correctly. After that I want to manipulate this equality, for example by substituting Taylor series of N instead of it. In Maple this whole thing is very straightforward, but I really can't find a way to do the same in Sage. Any help will be much appreciated.
