Abstract:The lattice CongFormula of all dynamic congruences on a given dynamic algebra Formula is presented. Whenever Formula is separable with zero we define dynamic ideal on Formula, given rise to the lattice IdeFormula. The notions of kernel of a dynamic congruence andthe congruence generated by a dynamic ideal are introduced todescribe a Galois connection between CongFormula and IdeFormula. We study conditions under which a dynamic congruence is determined byits kernel.
Keywords:Boolean algebra with operators  dynamic algebra  dynamic congruence  dynamic ideal  Galois connection
