The Serre spectral sequence in bounded cohomology

Kevin Li, Marco Moraschini, George Raptis

We construct the analogue of the Serre spectral sequence for the bounded cohomology of simplicial sets with seminormed local coefficients. As applications, we obtain a (non-isometr…

Some remarks on acyclicity in bounded cohomology

Marco Moraschini, George Raptis

We show that a surjective homomorphism $I ¨ : I^ \to K$ of (discrete) groups induces an isomorphism $H_{b}^{∙} (K; V) \to H_{b}^{∙} (I^; I ¨ ^{- 1} V)$ in bounded cohomology for a…
