Source abstract

We study the behaviour of partially de Rham Selmer groups of BB-pairs along abelian pp-adic Lie extensions. In the cyclotomic case we compare them with the universal norms studied by Berger. For analytic Lubin--Tate (φ,Γ)(\varphi,Γ)-modules we prove that the Ψ=1Ψ=1 eigenspace is coadmissible of the expected rank over the algebra of analytic distributions and establish a comparison result between its Lie-algebra coinvariants and the projective limit of the partially de Rham Selmer groups of the attached BB-pair.
