Abstract

For any prime pp and ε>0\varepsilon>0 we prove that for any sufficiently large positive odd integer ss at least (cpε)slogs(c_p-\varepsilon) \sqrt{\frac{s}{\log s}} of the pp-adic zeta values ζp(3),ζp(5),,ζp(s)\zeta_p(3),\zeta_p(5),\dots,\zeta_p(s) are irrational. The constant cpc_p is positive and does only depend on pp. This result establishes a pp-adic version of the elimination technique used by Fischler--Sprang--Zudilin and Lai--Yu to prove a similar result on classical zeta values. The main difficulty consists in proving the non-vanishing of the resulting linear forms. We overcome this problem by using a new irrationality criterion.
