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. 000079120 536__ $$9info:eu-repo/grantAgreement/ES/AEI-FEDER/MTM2017-83506-C2-1-P 000079120 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079120 590__ $$a0.857$$b2018 000079120 591__ $$aMATHEMATICS, APPLIED$$b172 / 254 = 0.677$$c2018$$dQ3$$eT3 000079120 591__ $$aPHYSICS, MATHEMATICAL$$b46 / 55 = 0.836$$c2018$$dQ4$$eT3 000079120 592__ $$a0.4$$b2018 000079120 593__ $$aApplied Mathematics$$c2018$$dQ3 000079120 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079120 700__ $$0(orcid)0000-0002-8667-1598$$aRodrigo-Escudero, A.$$uUniversidad de Zaragoza 000079120 7102_ $$12006$$2005$$aUniversidad de Zaragoza$$bDpto.
