Résumé | This work deals with general linear conservative neutron transport semigroups without spectral gaps in L-1(T-n x R-n) where T-n is the n-dimensional torus. We study the mean ergodicity of such semigroups and their strong convergence to their ergodic projections as time goes to infinity Systematic functional analytic results are given. |
