We call them spin-cube models, since they are categorical generalizations of spin-foam models. A spin-cube state sum can be considered as a path integral for a constrained 2-BF theory, and depending on how the constraints are imposed, a spin-cube state sum can be reduced to a path integral for the area-Regge model with the edge-length constraints, or to a path integral for the Regge model. We also show that the effective actions for these spin-cube models have the correct classical limit. <\/jats:p>","DOI":"10.1142\/s0129055x13430083","type":"journal-article","created":{"date-parts":[[2013,11,10]],"date-time":"2013-11-10T21:08:45Z","timestamp":1384117725000},"page":"1343008","source":"Crossref","is-referenced-by-count":12,"title":["SPIN-CUBE MODELS OF QUANTUM GRAVITY"],"prefix":"10.1142","volume":"25","author":[{"given":"A.","family":"MIKOVI\u0106","sequence":"first","affiliation":[{"name":"Departamento de Matem\u00e1tica, Universidade Lus\u00f3fona de Humanidades e Tecnologias, Av. do Campo Grande, 376, 1749-024 Lisboa, Portugal"},{"name":"Grupo de Fisica Matem\u00e1tica da Universidade de Lisboa, Av.
