On an Exceptional Phenomenon in Certain Quadratic Extensions

Canadian Journal of Mathematics, 1954
Let Ω be a cyclic extension of degree l over the field Σ. Correcting an error which for some time had been haunting the literature, Hasse (1, p. 272) noted that for l = 2, the field Ω may contain a unit ξ such that.

Spheres of quadratic field extensions

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 1994
Sei \(L\) eine nichtkommutative quadratische Körpererweiterung des kommutativen Körpers \(K\). Der Autor stellt dann die projektive Gerade über \(L\) als Spread \(\varphi_{L/K}\) im dreidimensionalen projektiven Raum \(P\) über \(K\) dar. Als Menge von Geraden kann \(\varphi_{L/K}\) als Punktmenge auf der Kleinschen Quadrik im fünfdimensionalen ...

Growth of torsion in quadratic extensions of quadratic cyclotomic fields

2015
Let K = ?(?(-3)) or ?(?(-1)) and let C_n denote the cyclic group of order n. We study how the torsion part of an elliptic curve over K grows in a quadratic extension of K. In the case E(K)[2] = C? ? C? we determine how a given torsion structure can grow in a quadratic extension and the maximum number of extensions in which it grows.
