Abstract
Let be an inclusion of -adic Lie groups. When is normal or even subnormal in , the Hochschild-Serre spectral sequence implies that any continuous -module whose -cohomology vanishes in all degrees also has vanishing -cohomology. With an eye towards applications in -adic Hodge theory, we extend this to some cases where is not subnormal, assuming that the -action is analytic in the sense of Lazard.
