摘要：

For a category Bwith finite products, we first characterizepseudofunctors fromBtoCatwhose associated opfibration is Cartesianmonoidal. Among those, we then characterize the ones which extend topseudofunctors from internal groups to 2-groups. IfBis additive, this isthe case precisely when the associated opfibration has groupoidal fibres.
