Markoff triples and Nielsen equivalence in $SL_{2} (F_{p})$

Daniel E. Martin

In 2013, Darryl McCullough and Marcus Wanderley made a series of conjectures that describe the Nielsen equivalence classes and $T_{2}$ -equivalence classes of pairs of generators for…

A new proof of Chen's theorem for Markoff graphs

Daniel E. Martin

In 2021, Chen proved a congruence for the degree of a certain map on the space of covers of elliptic curves. He concluded as a corollary that the size of any connected component of…

Lower bounds on the $ℓ$ -rank of ideal class groups

Daniel E. Martin

For a prime number $ℓ$ and an extension of number fields $K / F$ , we prove new lower bounds on the $ℓ$ -rank of the ideal class group of $K$ based on prime ramification in $K / F$ …
