WebA manifold solid B-rep is a finite, arcwise connected volume bounded by one or more surfaces, each of which is a connected, oriented, finite, closed 2-manifold. There is no restriction on the genus of the volume, nor on the number of voids within the volume. WebTherefore, the orientation character is given by the surjection . If is an embedding of a manifold of the same dimension (possibly with boundary), then the orientation …

WebLet X be an n-manifold. A fundamental class of X at a subspace A ⊂ X is an element s ∈ Hn(X,X −A) whose image Hn(X,X −A) → Hn(X,X −x) defines a local orientation for eachx ∈ A. When A = X, s ∈ Hn(X) is called a fundamental clas of X. Our next goal is to show that there exists a canonical fundamental class for each compact subset ...
