QFT for Mathematicians 2022 : a partially pedagogical workshop at the Perimeter Institute for Theoretical Physics, to take place on June 20-30, 2022.

The workshop is in part a follow-up to QFT for Mathematicians 2019. It is especially aimed at mathematicians — at all levels from advanced graduate students to senior faculty — who wish to tear down the language and communication barriers between mathematics and quantum field theory. This year we will focus on algebraic, geometric, and homological structures in supersymmetric gauge theories. We will use 3-dimensional N=4 gauge and N=2 theories --- which have seen an explosion of interest in both physical and mathematical communities in recent years --- as a key source of new examples exploring their connections with integrability, boundary vertex algebras and elliptic cohomology, knot homology, 2d mirror symmetry, and the geometric Langlands program.

The week of June 20-24, the workshop will run in hybrid mode, with most speakers and some attendees on site in Waterloo, and others participating remotely. This first week will be pedagogical ; everyone is welcome to apply to join in-person. The following week, June 27-30, the workshop will continue entirely online.

In order to attend either in-person or online, you must register/apply at .

Confirmed in-person speakers and discussion leaders the first week include : Mykola Dedushenko Justin Hilburn Natalie Paquette Lev Rozansky as well as members of the organizing committee : Kevin Costello Tudor Dimofte Davide Gaiotto Ben Webster Philsang Yoo

As part of the ACPMS Seminar is organised a special 1-day seminar :

The amplituhedron : algebra, combinatorics, and physics (www)

Thu, April 8, 2021

Computing amplitudes is the central objective in high-energy physics. For decades, the procedure of summing over Feynman diagrams in perturbative quantum field theory was the name of the game. However, performing this task in practice is severely hampered by the combinatorial explosion of the number of these diagrams. In 2013, N. Arkani-Hamed and J. Trnka introduced the amplituhedron, which proposes a fruitful geometric-combinatorial approach to computing (tree-level) amplitudes. Relating them to volumes of certain polytopes in the realm of Grassmannians opens up the possibility of a severe reduction in computational complexity.

This 1-day series of seminar talks aiming at making the underlying mathematics (and the bridge to physics) transparent for an interested audience.

All times CET (GMT+1) on Thu, April 8, 2021.

15:00–15:45 Steven Karp 16:00–16:45 Lauren Williams 17:15–18:00 Hugh Thomas 18:15–19:00 Thomas Lam

Sessions will be hosted via Zoom and/or

December 16-19, 2019 : Conference on Supergeometry, Supersymmetry and Quantization

Topics :

The conference will bring researchers across both the fields of mathematics and physics together in order to discuss recently developed topics, on-going work and speculative new ideas within supergeometry and its applications in physics. This event offers a unique opportunity to unite physicists and mathematicians who share a common interest in supermathematics. There will be enough time available for discussions between the participants ; a poster session for junior researchers will be organized. The main topics include :

- Supermanifolds and their generalizations (e.g., superschemes, color supermanifolds, noncommutative supergeometry...)
- Super Lie groups and Lie superalgebras
- Supergeometric methods in physics
- Geometric aspects of supersymmetric field theories, superstrings, and supergravity

The workshop "Mathematics of interacting QFT models", will take place in York (UK), 1-5 July 2019. The workshop will be hosted at King’s Manor, which is a lovely historical building right in the city centre.

Rigorous construction of interacting quantum field theory (QFT) models in 4 spacetime dimensions is one of the biggest challenges of mathematical physics. The aim of this workshop is to bring together experts working on different aspects of interacting QFT to present recent results and discuss perspectives for future directions. The main discussion topics will be :

- Axiomatic systems for QFT : progress in constructing interacting models.

- Renormalization : analytic and combinatorial aspects.

- Infrared problem : progress and perspectives.

If you are interested in participation, please contact the organizer : Dr. Kasia Rejzner ( There will be a limited number of contributed talk slots, so if you would like to propose a talk, please send the title and the abstract to the organizer as soon as possible and before the 1st May 2019.

Women at the Intersection of Mathematics and High Energy Physics 18 -20 Février 2019 ATTENTION inscriptions jusqu’au 15 février !

Elle fait suite à deux rencontres du même type :

“Women at the Intersection of Mathematics and High Energy Physics” 6-10 Mars 2017 MITP, Mainz (

“Women at the intersection of mathematics and theoretical physics” 9-12 Avril 2018 DESY Hamburg ( )

et part du constat que les femmes sont très peu présentes dans les domaines aux frontières des mathématiques et de la physique théorique. Ces rencontres ont pour objectif de contribuer à augmenter la visibilité des femmes qui s’aventurent dans ces domaines et à encourager d’autres à s’y aventurer et à renforcer les interactions fructueuses qui peuvent surgir aux marges des deux disciplines.

Ces rencontres mêlant des thématiques diverses, les exposés sont conçus de manière très pédagogique, permettent d’avoir un aperçu sur un thème de recherche actif sans connaissance préalable du domaine.

There will be a winter school on "Modular forms, periods and scattering amplitudes" at ETH Zurich, 11-15 February 2019, a joint activity of the ETH Institute for Theoretical Studies and SwissMAP. Please forward this to interested people, especially PhD students and postdocs. . More information and registration : . The focus is on themes of common interest to physicists and mathematicians and on cross-disciplinary dialogue. . The participation is free of charge but registration is required . Limited financial support for young participants is available. The deadline for applications for financial support on the online registration form is 31 December 2018. . There is the possibility to profit from preferential hotel rates if you reserve early. Information will appear soon under "Local information" on the website.

The 2019 Park City Mathematics Institute (PCMI) program "Quantum Field Theory and Manifold Invariants" It will take place June 30 - July 20, 2019 in Park City. PCMI is a vertically integrated institute : there is a Research Program, a Graduate Summer School, and various programs related to undergraduate students and faculty as well as a program for K-12 teachers. Therefore, we encourage you to share this message with colleagues, postdocs, and graduate students.

The Research Program offers large blocks of unstructured time for collaboration as well as organized seminars. New and recent PhDs are especially encouraged to apply as are small groups of collaborators from geographically separate areas. For more information, see :

The highly structured Graduate Summer School consists of several related minicourses :

1. Introduction to Gauge Theory (Andriy Haydys) 2. Introduction to Knot Theory (Jake Rasmussen) 3. Heegaard Floer Homology (Jennifer Hom) 4. Topological Quantum Field Theories/Knots and BPS states (Pavel Putrov) 5. Bordism categories, invertible field theories, and characteristic classes of smooth bundles (Soren Galatius) 6. BPS States and Spectral Networks (Andy Neitzke) 7. Advanced topics in (mathematical) gauge theory/Higgs bundles (Laura Schaposnik) 8. Floer homology (Tom Mrowka)

They vary in level of preparation needed, and the schedule is designed so there are good opportunities for students just entering the field as well as courses suitable for more advanced students. Each course is accompanied by a daily problem session, structured to help students develop facility with the material. For more information, as well as course descriptions, see :
