Simplicial embeddings
Webb10 maj 2024 · Iterated simplicial suspensions produce examples of d -dimensional complexes that are PL embeddable into \mathbb {R}^ {d+1} but do not admit a linear embedding. The difference between linear and PL embedding is even more dramatic. One can show that the problem of linear embeddability is algorithmically decidable. WebbThe 2 k + 1 result is a general result of Menger. The 2 k embedding problem is an algorithmic problem mentioned in the abstract. – i. m. soloveichik. Aug 29, 2012 at …

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. WebbWe consider 2-dimensional random simplicial complexes Y in the multiparameter model. We establish the multiparameter threshold for the property that every 2-dimensional …

Subsequently, the receiver decodes the structure and infers the missing or distorted data. The transmitter and receiver collaboratively train a simplicial convolutional autoencoder to accomplish the semantic … Webbto a simplicial isometric embedding of the whole space. Definitions.
