okay so we have to, In the Notation of this question http://www.mapleprimes.com/questions/201278-Fix-A-Syntax-Error-In-My-Simple-Function-please-Help , let f0 be contained in V be any given function and de ne
a sequence (fn) with n contained in (N subscript 0) of functions fn contained in V by

(f subscript 0) := f0  and   fn+1=Afn  for all n contained in (N subscript 0).


prove that this sequence converges pointwise, i.e. that for all   i,j contained in [N]X[N],
(f subscript infinity)(i, j) := (lim n-> infinity  fn(i, j)) exists and that "triangle"(f subscript infintiy) =0
and that
f1 = 0 :

any help would be much appreciated guys <3
