I should write the following formula:
This is the code:
\begin{equation}
Q_{sp}=\left\{\stackrel{\frac{\kappa_{0}\kappa_{1}\dots \kappa_{Zp-1}}{\mu_{1}\mu_{2}\dots\mu_{Zp} (1+\sum^{n}_{l=1} \frac{\kappa_{0}\kappa_{1}
\dots \kappa_{l-1}}{\mu_{1}\mu_{2}\dots \mu_{l}})} \dots 1\leq Zp\leq number\_pol}{\frac{1}{1+\sum^{n}_{l=1}\frac{\kappa_{0}\kappa_{1}
\dots \kappa_{l-1}}{\mu_{1}\mu_{2}\dots \mu_{l}}} \dots Zp=0}
\end{equation}
