Traditionally, the meeting consists of four onehour invited talks presented in a single day, a Saturday. In addition, a fifth speaker is invited to give a colloquium talk in the Ottawa  Carleton Institute of Mathematics and Statistics on the preceding Friday afternoon. The invited speakers, known for their eloquence of presentation and excellence in research, are chosen carefully to cover a broad range of topics and aspects of discrete mathematics. The Friday colloquium talk is addressed to a general audience of mathematicians.
The objective of the meeting is to gather researchers, postdoctoral fellows, and graduate students from the Ontario/Quebec area working in various fields of discrete mathematics in order to stimulate research collaboration in this vibrant interdisciplinary area. This year's speakers for the Discrete Mathematics Day lead research in the areas of graph theory, combinatorial structures, combinatorial enumeration, and algorithms. They have been involved in theoretical, applied, and algorithmic aspects of discrete mathematics.
The Discrete Math Workshop will run for 2 days this year, Friday
(May 25) and Saturday (May 26), and will include five onehour invited
talks by the above speakers as well as contributed talks.
