The MSRC regularly hosts Colloquium talks and research conferences. In this academic year, they typically take place on Monday between 4-5 pm in MAPTC/0G/018.

Speaker: Rachael Boyd (University of Southampton)
Title: "Symmetries of 3-Manifolds"
Abstract: "I’ll survey some known results on diffeomorphism group of 3-manifolds, where there is a nice interplay 
between geometric group theory and algebraic topology. There are various ways of decomposing a general 3-manifold into simpler pieces, and I will recall these, and discuss known consequences for the diffeomorphism groups. In the final minutes I’ll outline some of my joint work with Corey Bregman and Jan Steinebrunner, on the classifying space of the diffeomorphism group."

Date: 7-11 April 2025

The Mathematical Sciences Research Centre of the School of Mathematics and Physics at Queen's University Belfast will be hosting the mathematics workshop "Operads and Calculus" April 7-11. 

https://www.newton.ac.uk/event/ehtw02/

The focus of the Operads and Calculus Workshop is the equivariant homotopy theory that comes from two sources:

• Equivariant operads: generalisations of operads to G-spaces and (ring) G-spectra and associated algebraic-representation theoretic constructions such as incomplete Mackey and (bi)-incomplete Tambara functors.
• Functor calculus: particularly those constructed by Goodwillie, Weiss and Johnson-McCarthy, alongside equivariant generalisations and modern descriptions in terms of infinity categories and operads.

This invitation-only event will report on new developments and introduce researchers to the area, with an emphasis on early-career mathematicians. There will be two introductory lecture series (3 hours each): one series on equivariant operads, given by Mike Hill, and the other on homotopy calculus, given by Kristine Bauer. Invited and contributed talks will focus on recent advances and new directions.

Organisers: 

• David Barnes Queen's University Belfast
• Andrew Blumberg Columbia University
• Michael Ching Amherst College
• Magdalena Kedziorek Radboud Universiteit Nijmegen
• Sarah Whitehouse University of Sheffield
