WebIn topology and related branches of mathematics, a connected space is a topological space that cannot be represented as the union of two or more disjoint non-empty open subsets. Connectedness is one of the principal topological properties that are used to distinguish topological spaces. Web(9.16) A path-connected space is connected. (The converse fails.) (9.57) Let X be a path-connected space and let U, V ⊂ X be disjoint open sets such that U ∪ V = X. If they are both nonempty then we can pick a point x ∈ U and y ∈ V. By path-connectedness, there is a continuous path γ from x to y. indiana football sectional draw https://americlaimwi.com
