Abstract
We show that the coadmissibility of the Iwasawa cohomology of an -analytic Lubin-Tate -module is necessary and sufficient for the existence of a comparison isomorphism between the former and the analytic cohomology of its Lubin-Tate deformation, which, roughly speaking, is given by the base change of to the algebra of -analytic distributions. We verify that coadmissibility is satisfied in the trianguline case and show that it can be ``propagated'' to a reasonably large class of modules, provided it can be proven in the \'etale case.
