International Day of Mathematics

The IDM Governing Board has decided the theme of the 2020 IDM, which will be "Mathematics is everywhere". The theme was proposed by our colleague at CMUC Jaime Carvalho e Silva, former Secretary General of ICMI.
Examples of topics related to the following sub-themes can be found in several languages on the IDM website:

Mathematics is everywhere in science and technology.
Mathematics is everywhere in the organization of the civilization.
Mathematics is essential to meet the UN Sustainable Development Goals.
Mathematics is everywhere in whatever you do.
Tell me about some activity or area and I will tell you where mathematics is.

The website will soon post material related to the theme "Mathematics is everywhere".

Mathematics Colloquium

Title: The search for simple modules

Stephen Donkin (The University of York, UK)

Wednesday, 20 November 2019, 15:00

Abstract: We trace some lines of the search for simple modules (equivalently irreducible representations) in the Lie type setting of highest weight theory. The story starts in the 1890s and 1900s with the work of Frobenius and Schur on symmetric groups and general linear groups. It continues with the work of Weyl and Brauer on other classical groups. The focus today is on the problem of finding the irreducible representations in characteristic p of groups of Lie type (where the analogues of the cases studied by Frobenius and Schur are still far from understood). We will mention inputs from areas of algebra and geometry and the recent spectacular counterexamples by Geordie Williamson to the long held conjecture by Lusztig describing the characters of the irreducible representations when the characteristic is not too small.

Stephen Donkin is a Professor at the University of York. He held positions at Durham, Warwick, Cambridge and Queen Mary, University of London, before joining the staff at York in 2005. His research interests are in Algebra, especially Lie type representation theory. He his currently an Editor of the Journal of Pure and Applied Algebra and a member of the EPSRC Peer Review College.

Seminar of Representation Theory and Related Areas: 8th Workshop

Coimbra, 16 November, 2019

The Seminar of Representation Theory and Related Areas started in 2010 and emerged from an informal seminar of mathematicians from the Maths Departments of the Universities of Coimbra, Lisboa and Porto, with research interests in Representation Theory of Groups and Algebras, as well as Combinatorics.

The group aims to pursue and develop interactions between Representation Theory, Geometry, Combinatorics and other relevant areas. Participation is open to anyone with interests in these and other related areas.

Invited speakers:
Steven Donkin (York University, UK)
Karin Erdmann (Oxford University, UK)
Manuel Saorín (Universidad de Murcia, Spain)

Organizers at CMUC:
Ana Paula Santana, Ivan Yudin

Research Seminar Program (RSP) - UC|UP Joint PhD Program in Mathematics

1st Session, Porto, 13 December, 2019

The Research Seminar Program is organized by the students of the UC|UP Joint PhD Program in Mathematics, and it is thought as an opportunity for them to present their research and to discuss each other's work.
During the academic year, the students meet from time to time, to present and to listen to talks about their current work and/or related topics. Visitors from other universities, PhD students or Postdoctoral researchers, are welcome to join.
The venue of the seminar interchanges between the math departments of the universities of Coimbra and Porto.

João Santos (PhD student at CMUC)
Diego Daltro (PhD student at Univ. Federal da Bahia, Brazil)

The Sixteenth Workshop on Numerical Ranges and Numerical Radii

Hotel Termas da Curia, 13-16 June, 2020

The purpose of the workshop is to stimulate research and foster interaction between researchers interested in the subject. The informal workshop atmosphere will facilitate the exchange of ideas from different scientific areas and, hopefully, the participants will be informed on the latest developments and new ideas. Background on the subject and on previous meetings may be found at the WONRA website, and also at the Wiki page for the history of the workshop and related meetings.

The venue will be the historic University of Coimbra, one of the oldest in Europe. The host is CMUC, with the collaboration of several other Portuguese research institutions.

Invited speakers:
• Yuri Bahturin (Canada)
• Georgia Benkart (USA)
• Alberto Elduque (Spain)
