Ottawa-Carleton Discrete Math Days 2016

May 26 - 27, 2016, Carleton University

Location: HP 4351 (Herzberg Laboratories, 4th floor, room 4351), Carleton University

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 2016 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.

Location

All talks will be in HP 4351 (Herzberg Laboratories, 4th floor, room 4351). To find Herzberg Laboratories search for building "HP" in the campus map.

FORMAT: The 2016 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.

We will be accepting 25-minute contributed talks in any area of discrete mathematics. We are interested in all areas of discrete mathematics. Topics include (but are not limited to) graphs, designs, enumeration, combinatorial optimization, finite fields, algorithms. Titles and abstracts (text or LaTex only please) should be sent to dmgroup (dmgroup at math dot carleton dot ca). Please include "Abstract DMD" in the subject line of your email. Deadline is Friday May 13, 2016.

We will be able to offer partial travel support to graduate students and postdocs. Applications should be sent to dmgroup (dmgroup at math dot carleton dot ca). Please include "Financial Support DMD" in the subject line of your email. Deadline for support for non-Ottawa students and postdocs is Friday May 6, 2016.
