Determining the dimension of a manifold
WebIn this paper we determine the metric dimension of n-dimensional metric (X;G)-manifolds. This category includes all Euclidean, hyperbolic and spherical manifolds as special cases. WebDec 11, 2016 · 15. The manifold is a mathematical concept. In mathematics, a manifold is a topological space that locally resembles Euclidean space near each point. More precisely, each point of an n -dimensional manifold has a neighbourhood that is homeomorphic to the Euclidean space of dimension n.
