In a Faa Di Bruno Formula there is an equation:
$m_1$+2*$m_2$+3*$m_3$+...n*$m_n$=n
Is there any general solution for this equation.
For example for $m_1$+$m_2$+$m_3$+...+$m_n$=n, there is a simple algorithm calculating this. Thanks, Gevorg.
I presume you want to solve this equation $\sum_{k=1}^{n}km_k=n$ for integer $m_k$ that sum to $s$. There is no general solution, valid for any $1\leq s\leq n$, but the problem can be reduced to a calculation of integer partitions, see Faa di Bruno's formula, lattices, and partitions (2005).
You want to have a simpler summation in Faa Di Bruno Formula by avoiding using specific Diophantine equation? See this referrences
