Abstract:
We give criterions for strong protomodularity and prove that the strong protomodularity of an algebraic theory is inherited by its models in a category with finite limits. We give examples of strongly protomodular theories with several constants: C*-algebras, rings, Heyting algebras and Boolean algebras.
