Discrete mathematics is a broad research area involving the study of properties, algorithms, and applications of mathematical structures built on discrete objects. The objective of this workshop is to gather researchers, postdoctoral fellows, and graduate students from the Ontario/Quebec area and beyond working in various fields of discrete mathematics in order to stimulate research collaboration in this vibrant interdisciplinary area.

The 2014 Ottawa-Carleton Discrete Mathematics Days will consist of invited talks and several sessions of contributed talks, while leaving time for informal discussion. The proposed invited speakers are distinguished for excellence in research in finite geometry, combinatorial designs, random graphs, graph theory, finite fields and combinatorial optimization. They have been involved in theoretical, applied, and algorithmic aspects of discrete mathematics.

FORMAT: The 2014 Carleton-Ottawa Discrete Mathematics Days will be a two-day event consisting of 6 invited talks and several sessions of contributed talks, while leaving time for informal discussion. Students and postdoctoral fellows are particularly encouraged to present their work at the meeting.

The Ottawa-Carleton Discrete Mathematics Days are the of fspring of the Carleton Discrete Mathematics Days, which began in 1978. Since 2002, the Ottawa - Carleton Discrete Mathematics Days have been held annually in the spring, alternating its location between Carleton University and the University of Ottawa, and have been (usually) supported by the Fields Institute.
