Author’s summary: In this article we give an improvement of the ultrametric Nevanlinna theory and apply these results to a problem of uniqueness for ultrametric meromorphic functions. We obtain a new construction of bi-urs’ of \(n\) elements for such functions for every \(n\geq 5\). In particular we find bi-urs’ of the form \((S_n,\{\infty\})\) where \(S_n\) is the set of the zeros of the polynomial \(R_n(x)= {(n-1)(n-2) \over 2}x^n-n(n-2) x^{n-1}+ {n(n-1) \over 2} x^{n-2} -c\) with \(n\geq 5\).
