Some remarks on connectors and groupoids in Goursat categoriesArticle

Authors: Marino Gran ; Diana Rodelo ORCID; Idriss Tchoffo Nguefeu

    We prove that connectors are stable under quotients in any (regular) Goursat category. As a consequence, the category $\mathsf{Conn}(\mathbb{C})$ of connectors in $\mathbb{C}$ is a Goursat category whenever $\mathbb C$ is. This implies that Goursat categories can be characterised in terms of a simple property of internal groupoids.
