论文摘要
我们证明了一个无扭转组的单层产品的freiheitssatz,其中伴侣最多具有音节长度。该结果对无扭转组的方程式有应用:特别是在某些过度分组中,最多有18个音节长度的单数方程式在18个中的奇异方程。
We prove a Freiheitssatz for one-relator products of torsion-free groups, where the relator has syllable length at most 8. This result has applications to equations over torsion-free groups: in particular a singular equation of syllable length at most 18 over a torsion-free group has a solution in some overgroup.
