Products of conjugacy classes and fixed point spaces
R Guralnick, G Malle - Journal of the American Mathematical Society, 2012 - ams.org
We prove several results on products of conjugacy classes in finite simple groups. The first
result is that for any finite nonabelian simple groups, there exists a triple of conjugate …
