These reflection morphisms are shown to induceequivalences between the corresponding representati...

This leads to an isomorphism of motivic Borel--Moorehomolog...

We describe duplicial objects in terms of the decalagecomonads, and we give a conceptual account of the construction of duplicialobjects due to B\"ohm and \c{S}tefan.This is done in ter...
