Division polynomials with Galois group SU3(3).2 = G2(2)
David P. Roberts
We use a rigidity argument to prove the existence of two related degree twenty-eight covers of the projective plane with Galois group SU3(3).2 = G2(2). Constructing corresponding t…
Lightly ramified number fields with Galois group
David P. Roberts
We specialize various three-point covers to find number fields with Galois group , , , or and light ramification in various senses. One of…
A database of number fields
John W. Jones, David P. Roberts
We describe an online database of number fields which accompanies this paper The database centers on complete lists of number fields with prescribed invariants. Our description her…
Polynomials with prescribed bad primes
David P. Roberts
We tabulate polynomials in Z[t] with a given factorization partition, bad reduction entirely within a given set of primes, and satisfying auxiliary conditions associated to 0, 1, a…
Hurwitz Monodromy and Full Number Fields
David P. Roberts, Akshay Venkatesh
We give conditions for the monodromy group of a Hurwitz space over the configuration space of branch points to be the full alternating or symmetric group on the degree. Specializin…
