The SIAM Conference on Discrete Mathematics (DM20), originally scheduled to take place June 1-4, 2020 at the DoubleTree by Hilton Portland, Portland, Oregon, U.S. has been rescheduled due to COVID-19. It will now take place July 20 - 23, 2021 in Spokane, Washington, U.S.

This is the meeting of the SIAM Activity Group on Discrete Mathematics.

The following meetings will be held jointly:

SIAM Annual Meeting (AN21)

SIAM Conference on Applied and Computational Discrete Algorithms (ACDA21)

SIAM Conference on Control and Its Applications (CT21)

SIAM Conference on Discrete Mathematics (DM21)

SIAM Conference on Optimization (OP21)

Discrete mathematics is a branch of the mathematical sciences, with a wide range of challenging research problems and important applications in industry. Discrete mathematics has applications to all fields of computer science, and to the physical and biological sciences. It is used extensively in telecommunications, information processing, and manufacturing, and many businesses and industries use techniques of discrete optimization to improve the efficiency of their operations.

Discrete mathematics is a dynamic field in both theory and applications. Researchers in discrete mathematics have established important connections with mainstream areas of pure and applied mathematics, and as a consequence, research techniques and problems are drawn from a wide range of different fields, including algebra, topology, geometry, probability, analysis and logic.

The purpose of this conference is to highlight the major theoretical advances in the field, the development of new tools for discrete mathematics, and the most significant of the new applications of discrete mathematics to problems arising in industry and business. The conference also seeks to bring together participants from the many different environments where discrete mathematics is developed and applied.
