Explicit bounds on common projective torsion points of elliptic curves
Christian Böhning, Hans-Christian Graf von Bothmer, David Hubbard
Suppose E_1, E_2 are elliptic curves (over the complex numbers) together with standard double coverings of the projective line identifying a point and its inverse on E_i. Bogomolov…
Roots of unity and projective equivalence
David Hubbard
Existing results of Fu show that, if two finite sets of roots of unity are projectively equivalent by a projective automorphism that does not act bijectively on the set of all root…
Explicit computations in Iwasawa theory
Reinier Broker, David Hubbard, Lawrence C. Washington
We give two algorithms to compute layers of the anticyclotomic -extension of an imaginary quadratic field. The first is based on complex multiplication techniques for no…
Iwasawa Invariants of Some Non-Cyclotomic -extensions
David Hubbard, Lawrence C. Washington
Iwasawa showed that there are non-cyclotomic -extensions with positive -invariant. We show that these -invariants can be evaluated explicitly in many situations…
Kummer generators and lambda invariants
David Hubbard, Lawrence C. Washington
Let be an imaginary quadratic field with and let . Let be the fundamental unit of and let …
