Abstract
We establish an optimal (topological) irreducibility criterion for p-adic Banach principal series of \(\textrm{GL}_{n}(F)\), where \(F/\mathbb {Q}_p\) is finite and \(n \le 3\). This is new for \(n = 3\) as well as for \(n = 2\), \(F \ne \mathbb {Q}_p\) and establishes a refined version of Schneider’s conjecture (Schneider, P.: International congress of Mathematics, vol. II, pp. 1261–1282, 2006, Conjecture 2.5) for these groups.
