About the Journal


We publish research articles written in English in areas such as combinatorics and graph theory, discrete and computational geometry, discrete optimization and operations research, theoretical computer science, and coding and communication theory. In particular, the following topics (2000 AMS classification numbers in parentheses):

  • Mathematical logic and universal algebra (03B, 03C, 08)
  • Applications of logic to algebra and computer science (03B, 03D, 03G)
  • Set theory (03E)
  • Designs (05B, 51E)
  • Sphere packings, coverings and arrangements (05B, 52C)
  • Geometric and algebraic combinatorics (05E)
  • Partially ordered sets and lattices (06A, 06B)
  • Diophantine approximation (11J)
  • Cryptography, especially algebraic and number theoretic methods (11T, 14G)
  • Computational number theory (11Y)
  • Linear and nonlinear equations in matrices and operators (15A, 47A, 47J)
  • Discrete geometry including the theory of polytopes and rigidity (32F, 52B, 52C)
  • Operator theory with discrete aspects (46N, 47A)
  • Combinatorial and finite geometry (51D, 51E)
  • Computational geometry including computational convexity (52B, 65D)

Open Access Policy

This journal provides open access to all of it content on the principle that making research freely available to the public supports a greater global exchange of knowledge. Such access is associated with increased readership and increased citation of an author's work. For more information on this approach, see the Public Knowledge Project, which has designed this system to improve the scholarly and public quality of research, and which freely distributes the journal system as well as other software to support the open access publishing of scholarly resources.


This journal utilizes the LOCKSS system to create a distributed archiving system among participating libraries and permits those libraries to create permanent archives of the journal for purposes of preservation and restoration. More...
