Working paper, Department of Mathematics, Harvard University.http://nrs.harvard.edu/urn-3:HUL.InstRepos:30774536Fumiyuki Momose is very much missed. He was a generous warm human being, with immense energy and generosity of spirit, and an extremely gifted mathematician. One of his abiding interests was rational torsion on elliptic curves over number fields, as in [32], [24]. This article is written in his memory.en-USResearch Paper or Report2017-03-14
