These presentations should introduce the student’s research to a general mathematical audience. If requested by the presenter, an experienced mentor will be available to provide feedback on the talk. Any questions about the student sessions should be directed to the student session organizers, Muhammad Khan and Kyle MacDonald, at studc-summer16-session@cms.math.ca To register for the session, contact the organizers of the session with a draft abstract by April 30th.Notice of acceptance will be given by May 2nd. Abstracts submitted after this deadline will be considered if space remains. Presenters will also have to register for the meeting, which can be done through this form. Student members of the CMS who are presenting a poster or talk have significantly reduced registration costs (\$30 until May 6th, \$45 thereafter). If you are not currently a member of the CMS, talk to your department chair about the possibility of becoming a university-sponsored student member for a reduced fee. There is a limited amount of travel support available for graduate students. The deadline for applications to this fund is April 30th. The application form is available here and more information on these funds can be found on this page.
