Title: A new invariant for difference fields
Abstract: If (K,f) is a difference field, and a is a finite tuple in some difference field extending K, and such that f(a) in K(a)^{alg}, then we define dd(a/K)=lim[K(f^k(a),a):K(a)]^{1/k}, the distant degree of a over K. This is an invariant of the difference field extension K(a)^{alg}/K. We show that there is some b in the difference field generated by a over K, which is equi-algebraic with a over K, and such that dd(a/K)=[K(f(b),b):K(b)], i.e.: for every k>0, f(b) in K(b,f^k(b)).

Viewing Aut(K(a)^{alg}/K) as a locally compact group, this result is connected to results of Goerge Willis on scales of automorphisms of locally compact totally disconnected groups. I will explicit the correspondence between the two sets of results.

(Joint with E. Hrushovski)

Speaker: Laura Ciobanu
Title: Free group homomorphisms and the Post Correspondence Problem
Abstract: The Post Correspondence Problem (PCP) is a classical problem in computer science that can be stated as: is it decidable whether given two morphisms g and h between two free semigroups A and B, there is any nontrivial x in A such that g(x)=h(x)? This question can be phrased in terms of equalisers, asked in the context of free groups, and expanded: if the `equaliser’ of g and h is defined to be the subgroup consisting of all x where g(x)=h(x), it is natural to wonder not only whether the equaliser is trivial, but what its rank or basis might be.

While the PCP for semigroups is famously insoluble and acts as a source of undecidability in many areas of computer science, the PCP for free groups is open, as are the related questions about rank, basis, or further generalisations. However, in this talk we will show that there are links and surprising equivalences between these problems in free groups, and classes of maps for which we can give complete answers. This is joint work with Alan Logan.

Words of Women in Mathematics in the Time of Corona

This message addressed to women in mathematics around the world is to invite you to contribute to a follow up project
“Words of Women in Mathematics in the Time of Corona” of the video project “Faces of Women in Mathematics“. You might have contributed to that 2018 film project. If so, and if you did your clip as a group, please share this mail with your colleagues who were in the clip! Otherwise, you are also strongly encouraged to take part in this new project.

The “Faces of Women in Mathematics” film collected 146 clips of 243 women mathematicians from 36 different countries speaking 31 different languages. This very successful project has contributed to making women working in mathematics more visible and has received very positive resonance from the general public.

Three years later and with a year of pandemic behind us, we are launching a follow-up of the project, with the above working title “Words of Women in Mathematics in the Time of Corona”. The pandemic has made women and in particular women in mathematics more invisible than ever, and this project aims to let them be heard and seen. The new film will be launched on May 12th, Maryam Mirzakhani’s birthday that has become a day to celebrate Women in Maths.

We would like to invite you to contribute in answering the following question. “How has the pandemic affected your personal or professional life as a mathematician?” in the form of

  • a video clip (8-30 seconds in your original language) with your answer (preferably) in your native language to the above question OR a portrait photograph of yourself + audio file (use memo function of you cell phone) with your answer in your native language. The photograph should be a “natural” one, not an official “professional” one. Here is a link with some samples: http://vimeo.com/showcase/8239660
  • a written translation in English of your spoken words, as well as your first name, last name, the name of the language in which you made your statement and the country where you live and work We encourage you to add a photograph of your work space during the pandemic in high resolution, that we would include in the video.

We need to receive your contributions by April 21st 2021

Please send your clip to Irina Linke preferably by Wetransfer for highest resolution [https://wetransfer.com/]

Here are some practical recommendations for best video results:

  •      You may ask someone else to hold the camera and film you
  •      Use the camera of your smart phone; do not use the computer!
  •      Hold the camera at eye level
  •      Make sure that your face is well lit.
  •      For editing purposes, wait a few seconds before you start talking,and wait a few seconds before you stop filming after having said your sentence
  •      You may film outdoors
  •      Please check the clip for clarity of the sound, and try to avoid filming in a noisy or windy environment.

If you have any further questions, please don’t hesitate to contact us. We are very much looking forward to seeing and hearing your contributions! Please forward this call to whoever might be interested in contributing! Many thanks!

Take care,

Best wishes,

Sylvie and the team:

  • Eugenie Hunsicker (Mathematician, UK)
  • Irina Linke (Documentary filmmaker, Germany)
  • Sonia Mahmoudi (Mathematician, Japan)
  • Claudia Malvenuto (Mathematician, Italy)
  • Sylvie Paycha (Mathematician, Germany)
  • Eriko Shinkawa (Mathematician, Japan)

SMRI Seminar 8th April 2021

The Symmetry in Newcastle Seminar is not back just yet, but that does not mean you have to miss out on your monthly fix of Australian group theory seminars! Our friends at Sydney Mathematical Research Institute (SMRI) are hosting a seminar this Thursday and if you like combinatorial and geometric group theory, this might be just the event for you because the speakers for the day are Adam Piggott, Australian National University, and Murray Elder, University of Technology Sydney. The times, titles and abstracts of the talks, along with important links are as follows.

When: 8 April 2021, 15:00-17:00 AEST (05:00 – 07:00 UTC)

Where: Quad Oriental Room S204 (University of Sydney staff, students and affiliates only) and via Zoom (registration link below)

Talk 1: 15:00 AEST (05:00 UTC)

‘Stubborn conjectures concerning rewriting systems, geodesic normal forms and geodetic graphs’ 
Adam Piggott (ANU)

Abstract: A program of research, started in the 1980s, seeks to classify the groups that can be presented by various classes of length-reducing rewriting systems. We discuss the resolution of one part of the program (joint work with Andy Eisenberg (Temple University), and recent related work with Murray Elder (UTS).

Talk 2: 16:00 AEST (06:00 UTC)
‘Which groups have polynomial geodesic growth?’ 
Murray Elder (UTS)

Abstract: The growth function of a finitely generated group is a powerful and well-studied invariant. Gromov’s celebrated theorem states that a group has a polynomial growth function if and only if the group is {\em virtually nilpotent}. Of interest is a variant called the {\em geodesic growth function} which counts the number of minimal-length words in a group with respect to some finite generating set. I will explain progress made towards an analogue of Gromov’s theorem in this case. I will start by defining all of the terms used in this abstract (finitely generated group; growth function; virtual property of a group; nilpotent) and then give some details of the recent progress made.

The talk is based on the papers arxiv.org/abs/1009.5051arxiv.org/abs/1908.07294 and arxiv.org/abs/2007.06834 by myself, Alex Bishop, Martin Brisdon, José Burillo and Zoran Šunić.

Statement on the Inequitable Impacts of the Covid-19 Pandemic

The Australian Mathematical Society and the Statistical Society of Australia have released a joint statement on the unequal impacts of the Covid-19 pandemic on the profession. This is to reinforce, and add Australian context to, the statement released by the European Women in Mathematics group.

The Australian mathematical sciences community reiterates that the impacts of the Covid-19 pandemic have not been equally experienced, and they will continue to be felt for a long time to come. Impacts including reduction of research output, loss of networking opportunities and collegiate connection, and increased stress on mental health have been devastating to many, but have been most acutely felt by those in more vulnerable positions.

The full statement can be found on this page, or in (printable, accessible) pdf format here. It is endorsed by the ARC Centre of Excellence for Mathematical & Statistical Frontiers, the Australian Academy of Science, the Australian Academy of Technology and Engineering, the Australian Mathematical Sciences Institute, the Mathematical Research Institute (MATRIX), the National Tertiary Education Union, the University of Sydney Mathematical Research Institute, and Science & Technology Australia.
