Everywhere ramified towers of global function fields
Iwan Duursma, Bjorn Poonen, Michael Zieve
We consider a tower of function fields F_0 < F_1 < ... over a finite field such that every place of every F_i ramified in the tower and the sequence genus(F_i)/[F_i:F_0] has a fini…

Coset bounds for algebraic geometric codes
Iwan M. Duursma, Seungkook Park
For a given curve X and divisor class C, we give lower bounds on the degree of a divisor A such that A and A-C belong to specified semigroups of divisors. For suitable choices of t…
