WebApr 28, 2024 · We explain here the definition of graph manifold (also called plumbed manifold) that we refer to. For details, one can consult the foundational articles [ 27, 40, 41 ], as well as the article [ 29] for a description of the so-called plumbing calculus and other topological considerations on graph manifolds. WebOne of the earliest approaches to manifold learning is the Isomap algorithm, short for Isometric Mapping. Isomap can be viewed as an extension of Multi-dimensional Scaling …
WebThis is proven by showing that the symmetric index j (f,x) = [i (f,x) + i (-f,x)]/2 is constant zero for odd dimensional geometric graphs, a result which holds for odd dimensional Riemannian manifolds.

Much of the data we encounter in the real world can be represented as directed graphs. In this work, we introduce a general family of representations for directed graphs through connected time-oriented Lorentz manifolds, called spacetimes in general relativity. Spacetimes intrinsically contain a causal structure that indicates whether ...
