Pettie", abstract = "We describe a deterministic minimum spanning tree algorithm running in time $O(m \alpha(m,n))$, where alpha is a natural inverse of Ackermann's function and m and n are the number of edges and vertices, respectively. This improves upon the $O(m \alpha(m,n) \log \alpha(m,n))$ bound established by Chazelle in 1997. A similar $O(m \alpha(m,n))$-time algorithm was discovered independently by Chazelle, predating the algorithm presented here by many months. This paper may still be of interest for its alternative exposition.", }
