Universidad de Zaragoza Clifford Algebras as Twisted Group Algebras and the Arf Invariant 2018 Access copy available to the general public Unrestricted Some connections between quadratic forms over the field of two elements, Clifford algebras of quadratic forms over the real numbers, real graded division algebras, and twisted group algebras will be highlighted. This allows to revisit real Clifford algebras in terms of the Arf invariant of the associated quadratic forms over the field of two elements, and give new proofs of some classical results. info:eu-repo/grantAgreement/ES/AEI-FEDER/MTM2017-83506-C2-1-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.857 2018 MATHEMATICS, APPLIED 172 / 254 = 0.677 2018 Q3 T3 PHYSICS, MATHEMATICAL 46 / 55 = 0.836 2018 Q4 T3 0.4 2018 Applied Mathematics 2018 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-8667-1598 Rodrigo-Escudero, A.
