Polyhedron intersection

Webis a finite polyhedron in H1(M,R). A basic result is: ... Since 1-cycles in general position on Mare disjoint, the intersection form on H2(X,R) restricts to zero on i(H1(M,R)). But the intersection form is non-degenerate, so it must admit a positive (and negative) subspace WebIf you want to concentrate specifically on polyhedron-polyhedron intersection detection, this problem has been studied since the classic 1980's paper by Dobkin and Kirpatrick (which …
