An account of the commutator operation associated with equational deductive systems is presented, with an emphasis placed on logical aspects of the commutator for equational systems determined by quasivarieties of algebras. The author discusses the general properties of the equationally-defined commutator, various centralization relations for relative congruences, the additivity and correspondence properties of the equationally-defined commutator, and its behavior in finitely generated quasivarieties. Presenting new and original research not yet considered in the mathematical literature, The Equationally-Defined Commutator will be of interest to professional algebraists and logicians, as well as graduate students and other researchers interested in problems of modern algebraic logic. 606 $aGroup theory 606 $aCommutative algebra 606 $aCommutative rings 606 $aAssociative rings 606 $aRings (Algebra) 606 $aGroup Theory and Generalizations$3https://scigraph.springernature.com/ontologies/product-market-codes/M11078 606 $aCommutative Rings and Algebras$3https://scigraph.springernature.com/ontologies/product-market-codes/M11043 606 $aAssociative Rings and Algebras$3https://scigraph.springernature.com/ontologies/product-market-codes/M11027 615 0$aGroup theory. 615 0$aCommutative algebra. 615 0$aCommutative rings. 615 0$aAssociative rings. 615 0$aRings (Algebra) 615 14$aGroup Theory and Generalizations. 615 24$aCommutative Rings and Algebras. 615 24$aAssociative Rings and Algebras. 676 $a510 700 $aCzelakowski$b Janusz$4aut$4http://id.loc.gov/vocabulary/relators/aut$0755628 906 $aBOOK 912 $a9910300242903321 996 $aThe Equationally-Defined Commutator$92502870 997 $aUNINA
