Abstract
The possible classes of balanced circles of a signed graph are characterized in two ways.

## Abstract New characterizations of triangulated and cotriangulated graphs are presented. Cotriangulated graphs form a natural subclass of the class of strongly perfect graphs, and they are also characterized in terms of the shellability of some associated collection of sets. Finally, the notion o
The key to Seymour's Regular Matroid Decomposition Theorem is his result that each 3-connected regular matroid with no R 10or R 12 -minor is graphic or cographic. We present a proof of this in terms of signed graphs.
## Abstract A circularβarc graph is the intersection graph of a family of arcs on a circle. A characterization by forbidden induced subgraphs for this class of graphs is not known, and in this work we present a partial result in this direction. We characterize circularβarc graphs by a list of minim
