Georg Scheffers

In mathematics, more specifically in category theory - especially in internal category theory - an internal category in a category $C$ with pullbacks consists of the following data: two $C$-objects $C_0,C_1$ named "object of objects" and "object of morphisms" respectively and four $C$-arrows $d_0,d_1:C_1\to C_0,e:C_0\to C_1,m:C_1{\times }_{C_0}{C}_1\to C_1$ subject to coherence conditions expressing the axioms of category theory.
