Wedge sum

In topology, the wedge sum is a "one-point union" of a family of topological spaces. Specifically, if X and Y are pointed spaces (i.e. topological spaces with distinguished basepoints x 0 {\displaystyle x_{0}} and y 0 {\displaystyle y_{0}} ) the wedge sum of X and Y is the quotient space of the disjoint union of X and Y by the identification x 0 ∼ y 0…
