Resumen de Few subpowers, congruence distributivity and near-unanimity terms

Petar Markovic, Ralph McKenzie

• We prove that for any variety $$\mathcal{V}$$, the existence of an edge-term (defined in [1]) and Jónsson terms is equivalent to the existence of a near-unanimity term. We also characterize the idempotent Maltsev conditions which are defined by a system of linear absorption equations and which imply congruence distributivity.
