Conceptwedge sum / wedge sums of spheres / 球面楔和
Wedge Sum
A topological operation that combines two topological spaces by selecting a basepoint in each and identifying them. The homology groups of the wedge sum equal the direct sum of the homology groups of the factors, enabling modular construction of topological spaces with arbitrary Betti number sequences.

The network width of the wedge-sum construction accumulates linearly with the Betti numbers.
