Geombinatorics
Geombinatorics is a mathematical research journal (ISSN 1065-7371) founded by Alexander Soifer and published by the University of Colorado, USA, since 1991 under an international board of editors (Ronald L. Graham, University of California, San Diego; Branko Grünbaum, University of Washington; Peter Johnson,Jr., Auburn University; Jaroslav Nešetřil, Charles University - Czech Republic; János Pach, Courant Institute of Mathematical Sciences and Heiko Harborth, Braunschweig University of Technology). It is devoted to problems in discrete, convex, and combinatorial geometry, as well as related areas.
Unlike many other mathematical journals, its articles feature a less formal style, making it more accessible for students.
Paul Erdős was an editor of and active contributor to Geombinatorics.
