The following papers are the latest research papers available from the Canadian Mathematical Bulletin.

The papers below are all fully peer-reviewed and we vouch for the research inside. Some items are labelled Author's Draft, and others are identified as Published.
As a service to our readers, we post new papers as soon as the science is right, but before official publication; these are the papers marked Author's Draft. When our copy editing process is complete and the paper now has our official form, we replace the Author's Draft with the Published version.
All the papers below are scheduled for inclusion in a Print issue. When that issue goes to press, the paper is moved from this Online First web page over to the main CMB Digital Archive.
