Jitendra Bajpai, Daniele Dona
We prove a version of Jordan's classification theorem for finite subgroups of that is at the same time quantitatively explicit, CFSG-free, and valid for arbitr…

Growth estimates and diameter bounds for untwisted classical groups
Jitendra Bajpai, Daniele Dona, Harald Andrés Helfgott
Babai's conjecture states that, for any finite simple non-abelian group , the diameter of is bounded by for some absolute constant . We prove that, for an…
