论文摘要
我们完全确定了所有自由对象的各种单体，所有完全不变的一致性或所有完全不变的一致性都包含在最小半质量的一致性中。在此过程中，我们发现了具有分布次级晶格的几种新的单体品种（到目前为止，只有一些具有这种特性的品种的示例）。
We completely determine all varieties of monoids on whose free objects all fully invariant congruences or all fully invariant congruences contained in the least semilattice congruence permute. Along the way, we find several new monoid varieties with the distributive subvariety lattice (only a few examples of varieties with such a property are known so far).
