WebbEffective Higher-order Link Prediction and Reconstruction from Simplicial Complex Embeddings belongs to the simplicial complex K(for any σ∈Kand τ⊂σ, we also have τ∈K). This constraint makes simplicial complexes different from hypergraphs, for which there is no prescribed relation between hyper-edges. Webb11. I know the homology group of Real Projective plane R P 2. H i ( R P 2) = 0 for i > 2, Z for i = 0 , Z / 2 Z for i = 1 (non-reduced case). Proving when i ≠ 2 is easy but i = 2 case is slightly hard for me. R P 2 has CW complex structure with one of each 0, 1, 2 cells so this takes care of i > 2 case and R P 2 is connected so it takes care ...

WebbThe method of this paper is based on studying simplicial embeddings and im-mersions of polyhedra into random 2-complexes. We analyze in detail the numerical invariants μ(S) and μ(S)˜ , deﬁned in Sect. 3, which play a crucial role in the ques-tions about the existence of embeddings and immersions. We also discuss the notion WebbIn this paper, isometric embedding results of Greene, Gromov and Rokhlin are extended to what are called "indefinite metric polyhedra".

WebbThe drawing routines in simplicial are based around the use of the simplicial.Embedding class, which specifies the embedding of a simplicial complex into a space. Various sub-classes of simplicial.Embedding provide different positionings, which the drawing sub-system then renders. WebbLet be two fields of characteristic 0.
