English
For any hT, q, the equality Quotient.mk'' (rightQuotientEquiv hT q) = q holds, expressing compatibility of the representative map with the quotient structure.
Русский
Для любого hT, q верно: Quotient.mk'' (rightQuotientEquiv hT q) = q, что выражает совместимость отображения выборочного представителя с фактор-структурой.
