OVERVIEW
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 OttawaCarleton 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 CarletonOttawa
Discrete Mathematics Days will be a twoday 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 OttawaCarleton 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. For more information
