给定任意群G,我们构造了一个幂等(带)半群BG,它具有BG上的自由幂等生成半群有一个与G同构的极大子群的性质。如果G是有限的,则BG是有限的。这回答了该领域最近论文中的几个问题。
Given an arbitrary group G we construct a semigroup of idempotents (band) BG with the property that the free idempotent generated semigroup over BG has a maximal subgroup isomorphic to G. If G is finitely presented then BG is finite. This answers several questions from recent papers in the area.
