May 14 – June 1, 2018 » Probability in Number Theory

Organizers: Andrew Granville (Montréal), Dimitris Koukoulopoulos (Montréal), Maksym Radziwill (McGill)

The appearance of Probability in Number Theory can be traced back to a famous collaboration of Erdős and Kac. Nowadays, probabilistic techniques are routinely used in the study of integers and L-functions. However, until recently there had not been much room for modern and deep techniques of probability theory. During the past few years this has changed notably. Conversely, number theoretic techniques and heuristics have been proven effective in resolving standing problems in combinatorics and discrete probability theory. The goal of this month-long program is to bring together experts from Number Theory and Probability to highlight and facilitate the interactions between these two fields of mathematics.

The first week of the program (May 14-18) will be dedicated to a summer school featuring lecture series by Kevin Ford (Illinois), Adam Harper (Warwick), and K. Soundararajan (Stanford). We seek applications from young researchers to attend the school. Priority will be given to advanced PhD students and early PhD graduates. We hope to be able to offer financial support of 800 CAD to each participant.

We would also like to invite applications for five junior members of the program, who will stay in residence for all three weeks of the program. Their travel and lodging expenses will be supported up to 2,000 CAD.

Please encourage any interested number theorists to apply by sending the following items:

1) Curriculum Vitae
2) A research statement of 1-2 pages explaining the research the applicant is working on and why they think they would benefit from the summer school.

3) Only for those applying to be a junior member of the program: two letters of recommendation

The application packages are to be submitted to Louis Pelletier via email at pelletl@crm.umontreal.ca. The deadline is January 21, 2018.

The remainder of the program will gather at CRM several of the leading experts in the fields of Probability and Number Theory. We also invite applications for five month-long postdoctoral positions (details to follow). Among other things, we will run a frequent research seminar for the participants of our program.

July 2 – 6, 2018 » A Celebration of CICMA’s Postdoctoral Program

Organizers: Henri Darmon (McGill), Andrew Granville (Montréal)

The goal of this workshop will be to host the CRM–ISM postdoctoral fellows who have worked in the Centre Interuniversitaire en Calcul Mathématique Algébrique (CICMA) over the last 30 years or so. CICMA includes researchers working in number theory, group theory, and algebraic geometry. The large majority of our postdoctoral fellows have launched successful academic careers of their own, and since then have maintained close ties with CICMA, contributing to its success by sending their students to Montréal and, in some cases, through continued exchanges and collaborations with permanent CICMA members. The CRM 50th anniversary provides an opportunity to bring these researchers back to Montréal and celebrate their achievements and contributions to the scientific life of the number theory group.

July 9 – 20, 2018 » Montréal Summer Workshop on Challenges in Probability and Mathematical Physics

Organizers: Alexander Fribergh (Montréal) , Louigi Addario-Berry (McGill), Omer Angel (British Columbia)

This event is similar to a short thematic semester. There will be a light schedule of talks, leaving a lot of free time to encourage collaborations between participants and promote discussions between members of different subfields in probability theory.

The central topic of the workshop will be random media, with an emphasis on the following themes: spin glasses, percolation problems in two dimensions, branching Brownian motions and log-correlated fields, Liouville quantum gravity, random walks in random environments and random graphs.

Each lecture day will be focused on one particular theme; speakers will be asked to focus their talks on open problems and tools that need to be developed in order to encourage collaborations between participants.

The workshop, a satellite activity of the XIX International Congress on Mathematical Physics that will be held in Montréal on July 23-28,  is jointly supported by the Centre de recherches mathématiques and by the Pacific Institute for the Mathematical Sciences.

September 10 – 28, 2018 » Faces of Integrability

Organizers: Jacques Hurtubise (McGill), Nicolai Reshetikhin (Berkeley), Lauren K. Williams (Berkeley)

The theory of integrable systems, with its origins in symmetries, has intricate ties to a wide variety of areas of mathematics. Sometimes the ties are straightforward, but in many cases, the links are more complicated, and indeed somewhat difficult to make explicit.  Some of these interfaces, between integrability, geometry, representation theory, and probability theory will be dominating subjects during the conference and satellite activities.  Themes to be covered include the role of cluster algebras and cluster varieties in the description of moduli spaces, the links between integrable systems and representation theory appearing in such areas as quantum groups and quantization of moduli spaces, and the fascinating interfaces of probability theory, combinatorics and integrable systems appearing in several processes linked to statistical mechanical models.

During the first week of activities, introductory lectures for graduate students will take place, as well as research seminars and discussions. The conference will take place during the second week. During the third week, research discussions and seminars will continue together with follow-up lectures for graduate students.

September 17 – October 14, 2018 » Algebra and combinatorics at LaCIM, a conference for the 50th anniversary of the CRM

Organizers: François Bergeron (UQAM),Srecko Brlek (UQAM), Christophe Hohlweg (UQAM)

escription: On the occasion of CRM’s 50th anniversary in 2018, the Laboratoire de Combinatoire et d’Informatique Mathématique (LaCIM) organizes a month of scientific activities to discuss the state-of-the-art and manifold interconnections between the lively topics that have long been at the core of research at LaCIM: algebraic combinatorics, combinatorial representation theory, Coxeter groups theory, combinatorics of words, discrete geometry, enumerative combinatorics, mathematical computer science and their applications. The scientific activities will be articulated around the confirmed participations of Mireille Bousquet-Mélou and Ezra Miller; together with a week-long international conference to be held from the 24th to the 28th of September 2018. This conference will be organized as follows:

* two days session dedicated to subjects related to ties between algebra and combinatorics;
* two days session dedicated to subjects related to ties between combinatorics, theoretical computer science, and statistical physics.

The bridge between the two sessions will be a special event on Wednesday 26th, aiming at underlying 30 years of partnership of LaCIM and CRM through 4 conferences given by:

* Mireille Bousquet-Mélou,
* Ezra Miller,

and by LaCIM’s past and current holders of the Canadian Research Chair, “Algebra, Combinatorics and Mathematical Computer Science”

* Christophe Reutenauer and
* Hugh Thomas.
