Exists pow smul integer mem span

IsNonarchimedeanLocalField.exists_pow_smul_integer_mem_span

Plain-language statement

Bounded denominators: if b is any finite K-basis of L and Ο– is a uniformiser of K, then a large enough power of Ο– multiplies every integer of L into the π’ͺ[K]-lattice spanned by b. This is the key analytic input both for Module.Finite π’ͺ[K] π’ͺ[L] (see below) and, applied to a normal basis, for the construction of an open cohomologi...
