Abstract
A quadrangulation is a spherical map of a simple graph such that each face is bounded by a cycle of length four. Since every quadrangulation G is bipartite, G has a unique bipartition V(G) = B ∪ W, where we call (|B|,|W|) the bipartition size of G. In this article, we shall prove that any two quadrangulations G and G′ with the same bipartition size can be transformed into each other by at most 10|B| + 16|W| − 64 diagonal slides.
