Axiomàtica dels nombres reals
(Universitat Politècnica de Catalunya, 2013-06)
Bachelor thesis
Open AccessL'objectiu d'aquest treball és estudiar les propietats del conjunt de nombres reals, començant per una construcció d'aquest conjunt a través de classes d'equivalència de successions de Cauchy. Posteriorment, es prendrà ... -

Hopf Galois structures on symmetric and alternating extensions
(2018)
Article
Open AccessBy using a recent theorem by Koch, Kohl, Truman and Underwood on normality, we determine that some types of Hopf Galois structures do not occur on Galois extensions with Galois group isomorphic to alternating or symmetric ... -
Induced Hopf Galois structures
(2016-07-01)
Article
Open AccessFor a ¿nite Galois extension K/k and an intermediate ¿eld F such that Gal(K/F)has a normal complement in Gal(K/k), we construct and characterize Hopf Galois structures on K/k which are induced by a pair of Hopf Galois ... -

Revisiting Kneser’s theorem for field extensions
(2017-05-31)
Article
Open AccessA Theorem of Hou, Leung and Xiang generalised Kneser’s addition Theorem to field extensions. This theorem was known to be valid only in separable extensions, and it was a conjecture of Hou that it should be valid for all ...
