内容简介

　　《字的有效性与群的幂零性》适合作为本科高年级学生的群论教材或参考资料，也可作为数学专业学生的双语课教材。幂零群是介于交换群与可解群之间的一类群，在群论中占有十分重要的位置。《字的有效性与群的幂零性》研究群的广义幂零性。幂零群被有限幂指数群的扩张群，是比幂零群范围更广的一类群；同时它们也遗传了许多幂零群的良好性质，因而对这类群的研究具有十分重要的意义。作者在自己研究成果的基础上，总结了多年来在该领域的一些典型成果，从群定律与群结构两方面论述了群的幂零性。《字的有效性与群的幂零性》分两部分。第一部分（2，3，4，5章）研究自由群及字（元素）的性质。第二部分研究群的结构。并着重研究了塌缩群，正定群，Milnor群，多项循环群sB一群等形态群的幂零性。
