To make a connection with our four-dimensional universe we need dimensional reduction to link a higher-dimensional theory to a lower-dimensional one. As a rst contact with the subject, we study how dimensional reduction works analyzing pure Einstein gravitation in D = d+1 dimensions, with an extra dimension compacti ed on S1. Finally, motivated by the presence of non- Abelian gauge groups in the Standard Model, we analyze extra dimensions compacti ed in some internal compact space, which give rise to gauge elds associated to these gauge groups.5 p.application/pdfengcc-by-nc-nd (c) Cardona Rotger, 2014http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teories del camp unificatTeoria de Kaluza-KleinTreballs de fi de grauUnified field theoriesKaluza-Klein theoriesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
