Hello i am relatively new to mathematica and i have a a problem regading my model.
I have following function:
P(t_) := P(t) = P(t – 1) + a* (df(t – 1) + dc(t – 1));
(df & dc are defined and not so important for this question.)
Now i want to restrict this function following the expression:
P(t)(1-i) < P(t+1) < P(t)(1+i)
i is supposed to go from 0 up to 0.13 for each period t.
For context, this function is supposed to represent prices in a market and i want to set up a price restriction.
