Hi,

I need help please, i wish to show that the following sequence of function converge to zero (for a given argument u): $$g_{n}\left( u\right) =B\left( u\right) g_{n-1}\left( a\left( u\right) \right) +A\left( u\right) g_{n-1}\left( u\right) $$, with the following conditions on function $$A$$ and $$a$$: $$a^{oh}\left( u\right) \rightarrow 0$$ when $$h\rightarrow \infty $$. $$\left| A\left( u\right) \right| <1$$. where $$a^{oh}$$ denotes a function compounded h times with itself.

Thanks

Bruno
