Bicircular signed-graphic matroids. (English) Zbl 1288.05035
Summary: A theorem of L. R. Matthews [Q. J. Math., Oxf. II. Ser. 28, 213–227 (1977; Zbl 0386.05022)] gives a characterization of graphs whose bicircular matroids are graphic. We give a characterization of graphs whose bicircular matroids are signed-graphic.
