Mathematical meanings of the term covering include

• A covering map in topology. In Mathematics, a covering space is a Topological space C which "covers" another space X by a Surjective Local homeomorphism Topology ( Greek topos, "place" and logos, "study" is the branch of Mathematics that studies the properties of
• Cover (topology), a system of (usually, open or closed) sets whose union is a given topological space. In Mathematics, a cover of a set X is a collection of sets such that X is a Subset of the union of sets in the collection Topological spaces are mathematical structures that allow the formal definition of concepts such as Convergence, connectedness, and continuity.
• A vertex covering or edge covering in graph theory. In the mathematical discipline of Graph theory, a covering (or cover) of a graph is a set of vertices (or edges such that each edge (vertex In the mathematical discipline of Graph theory, a covering (or cover) of a graph is a set of vertices (or edges such that each edge (vertex In Mathematics and Computer science, graph theory is the study of graphs: mathematical structures used to model pairwise relations between objects

• The Lebesgue covering dimension, a definition of dimension using topological properties. In Mathematics, the Lebesgue covering dimension or topological dimension of a Topological space is defined to be the minimum value of n, such In mathematics the dimension of a Space is roughly defined as the minimum number of Coordinates needed to specify every point within it
