We study the varieties with \(\vec {0}\) and \(\vec {1}\) where factor congruences are definable by existential formulas parameterized by central elements. This continues previous work on equational definability of factor congruences.

具有存在可定义因素同余的品种

我们研究了具有\(\vec {0}\)\(\vec {1}\)的变体,其中因子同余可以通过中心元素参数化的存在公式来定义。这延续了先前关于因子同余的方程可定义性的工作。
