*Title: *Critical surface for the multi-edges percolation model on oriented
homogeneous trees

*Abstract: *de Lima, Rolla and Valesin (2019) introduced and studied the
2-edges percolation model on homogeneous oriented trees $\mathbb T_d$. In
this model, small (length one) edges are opened with probability $p$ and
long (length $k>1$) edges are opened with probability $q$. Here, in the
slightly more general setting of m-edges ($m\ge2$), we obtain the critical
surface as the set of $0$'s of a specific polynomial with coefficients
depending on $d$. Specializing to the original 2-edges case, we can extract
bounds for the critical parameters, which are valid for any $d$ and $k$.
