Gallai's Conjecture For Graphs of Girth at Least Four
In 1966, Gallai conjectured that for any simple, connected graph G having n vertices, there is a path-decomposition of G having at most paths. In this article, we show that for any simple graph G having girth , there is a path-decomposition of G having at most paths, where is the number of vertices of odd degree in G and is the number of nonisolated vertices of even degree in G.
