The span-squares adjunction
George Raptis, Wolfgang Steimle
We show a universal property of the span -category that yields a description of functors defined on this category. For this, we view the span construction as a functor from…
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 of (discrete) groups induces an isomorphism in bounded cohomology for all d…
Some characterizations of acyclic maps
G. Raptis
We discuss two categorical characterizations of the class of acyclic maps between (path-connected) spaces. The first one is in terms of the higher categorical notion of an epimorph…
