Title
Bonds with parity constraints
Abstract
Given a connected graph G=(V,E) and three even-sized subsets A"1, A"2, A"3 of V, when does V have a partition (S"1,S"2) such that G[S"i] is connected and |S"i@?A"j| is odd for all i=1,2 and j=1,2,3? This problem arises in the area of integer flow theory and has theoretical interest in its own right. The special case when |A"1|=|A"2|=|A"3|=2 has been resolved by Chakravarti and Robertson, and the general problem can be rephrased as a problem on binary matroids that asks if a given triple of elements is contained in a circuit. The purpose of this paper is to present a complete solution to this problem based on a strengthening of Seymour@?s theorem on triples in matroid circuits.
