半群簇格的可消元：满足长度为3的置换恒等式的簇
Cancellable elements of the lattice of semigroup varieties: varieties satisfying a permutational identity of length 3
摘要：
我们完全确定了所有满足长度为3的置换恒等式的半群簇是所有半群簇的格的可消元。利用这个结果，我们提供了一系列新的例子，半群品种是一个模块，但不能取消的元素，这个格。
英文摘要：
We completely determine all semigroup varieties satisfiyng a permutational identity of length 3 that are cancellable elements of the lattice of all semigroup varieties. Using this result, we provide a series of new examples of semigroup varieties that are a modular but not cancellable elements of this lattice.
