Hi Raluca,

well, this is not Maple ...

You need to define an equation, i.e. it should read after RSolve x[t+1] == a[t] ... In a notebook both operators (= and ==) look very similar.

Regarding your question on multivariate recurrence: I may be completely wrong, but to me this seems equivalent to your first problem. In the solution there is nowhere stated that every element needs to be a scalar.

Hi,

what did you try ???

There is a function RSolve which is exactly made for this kind of task:

I tried in Maple because I have never used Mathematica.

I see it is better for this kind of problems.

You don't know how much you helped me. This recurrence stressed me a lot last couple of days.

Do you think I could resolve a multivariate recurrence like Lemma1 (page 5) from the same article?

Thank you so much.

Best wishes and regards,

Raluca
