Absolute Retracts and Amalgamation in Certain Congruence Distributive Varieties
Published online by Cambridge University Press: 20 November 2018
Abstract
It is shown that if V is a congruence distributive variety whose members have one element subalgebras, then the class of absolute retracts of V is closed under direct products. If V is residually small, then a characterisation of the amalgamation class of V is given.
