Note on the path‐matching formula
András Frank, László Szegő · Journal of Graph Theory · 2002
Abstract As a common generalization of matchings and matroid intersections, W.H. Cunningham and J.F. Geelen introduced the notion of path‐matchings. They proved a min‐max formula for the maximum value. Here, we exhibit a simplified version of their min‐max theorem and provide a purely combinatorial proof. © 2002 Wiley Periodicals, Inc.
