RT Journal Article T1 Mackey functors for posets A1 Carrión Santiago, Guille A1 Díaz-Ramos, Antonio K1 Algebras topológicas AB We define Mackey functors over posets mimicking the classical notion and introduce a weak version of them. Then we show that they are acyclic by analyzing cofibrant and pseudoprojective objects in the category of functors indexed in a filtered poset. As application, we study homotopy colimits over posets and we give a homology decomposition for the classifying space of the Bianchi group PB Springer Nature YR 2025 FD 2025-02-03 LK https://hdl.handle.net/10630/37787 UL https://hdl.handle.net/10630/37787 LA eng NO Carrión Santiago, G., & Díaz Ramos, A.
