Find the explicit form for the recurrence: $$b_{n+1}=\sum_{i = 1}^{n}{a_i b_{n-i+1}}$$ in terms of $a_k ;1 \leq k \leq n,b_0,b_1$
$\textbf{This is a very special recurrence}$............... The case $a_j=b_j$ symbolises the number of ways to put brackets in the expression : $$k_1 \times k_2 \times \cdots \times k_n$$ It also gives the coefficient of the power series defined by : $$F(x)=\sum_{j = 1}^{\infty}{a_j x^j}$$ as, $$\frac{1}{F(x)}=\sum_{j =1}^{\infty}{b_j x^j}$$ It is extreme sophisticated so I am not able to apply any of the methods of characteristic equation etc... Do these kind of recurrence have a special name?
