Abstract
An important theorem due to Truemper characterizes the graphs whose edges can be labelled so that all chordless cycles have prescribed parities. This theorem has since proved an essential tool in the study of balanced matrices, graphs with no even length chordless cycle and graphs with no odd length chordless cycle of length greater than 3. In this paper we prove this theorem in a novel and elementary way and we derive some of its consequences. In particular, we show how to obtain Tutte’s characterization of regular matrices.
