The computation for compact surfaces depends on a highly refined topological tools, however in the case of convex polyhedra this invariant is constant equal to two and it follows, because convex polyhedra are homeomorphic to a sphere, from a simple verification of the formula which relates the number of vertices V, the number of edges A and the number of faces F of a polyhedron, more precisely, V − A + F = 2 (Euler’s Formula). In this work we present a proof, using only finite induction, for the computation this invariant taking into account, however, only a class of non-convex polyhedra, presented in a specific way, here called n-toric polyhedra, which are homeomorphic to an n-torus.","PeriodicalId":274953,"journal":{"name":"Revista Professor de Matemática On line","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126470760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
