Для таких полуколец исследуются уравнительные свойства (теоремы 7, 8, 10, предложение 12). Полученные результаты применены к дистрибутивным решеткам (предложения 15, 16, 17). Приведены примеры и поясняющие замечания.</p></abstract><trans-abstract xml:lang="en"><p>We study one class of semirings close to distributive lattices, namely: semirings with commutative idempotent multiplication, satisfying the identity x + 2xy = x. For such semirings, the equalizing properties are investigated (Theorems 7, 8, 10, Proposition 12). The results obtained can be applied to distributive lattices (Propositions 15, 16, 17).
