Definition
A geometric morphism p : ℰ → 𝒮 p:\mathcal{E} \to\mathcal{S} (, or the 𝒮 \mathcal{S} -topos ℰ \mathcal{E} it corresponds to) is called grouplike if for every 𝒮 \mathcal{S} -topos q : ℱ → 𝒮 q:\mathcal{F} \to\mathcal{S} the category of 1-cells from q q to p p in the 2-category Top / 𝒮 \mathbf{Top}/\mathcal{S} of 𝒮 \mathcal{S} -toposes is a groupoid .
