Non-simple abelian varieties in a family: geometric and analytic approaches

J. Ellenberg, C. Elsholtz, C. Hall +1

Let be a family of abelian varieties over a number field parametrized by a rational coordinate , and suppose the generic fiber of is geometrically simple. For ex…

Monodromy Groups of Hurwitz-type Problems

Daniel Allcock, Chris Hall

We solve the Hurwitz monodromy problem for degree-4 covers. That is, the Hurwitz space H_{4,g} of all simply branched covers of P^1 of degree 4 and genus g is an unramified cover o…

Big symplectic or orthogonal monodromy modulo l

Chris Hall

Let k be a field not of characteristic two and L be a set of almost all rational primes invertible in k. Suppose we have a variety X/k and strictly compatible system {M_ell -> X :…
