• Resumen

  • As J. W. Snow showed, every linear Mal�tsev condition on a variety $${\mathcal{V}}$$ of universal algebras, is equivalent to a relational condition on $${\mathcal{V}}$$. Using slightly different relational reformulations of linear Mal�tsev conditions, we develop a purely categorical approach to these conditions.
