An effective version of a theorem of Habegger

Gareth Jones
(Manchester)
Abstract

Habegger showed that a subvariety of a fibre power of the Legendre family of elliptic curves contains a Zariski-dense set of special points if and only if it is special. I'll explain this result, and discuss an effective version that Gal Binyamini, Harry Schmidt, Margaret Thomas and I proved.

A group action version of the Elekes-Szabó theorem

Martin Bays (Oxford)
Abstract

I will present a generalisation of the Elekes-Szabó result, that any ternary algebraic relation in characteristic 0 having large intersections with (certain) finite grids must essentially be the graph of a group law, to a version where one obtains an algebraic group action. In the end the conclusion will be similar, but with weaker assumptions. This is recent work with Tingxiang Zou.

The model theory of the real and complex exponential fields

Alex Wilkie (Manchester/Oxford)
Abstract

A key ingredient in the proof of the model completeness of the real exponential field was a valuation inequality for polynomially bounded o-minimal structures. I shall briefly describe the argument, and then move on to the complex exponential field and Zilber's quasiminimality conjecture for this structure. Here, one can reduce the problem to that of establishing an analytic continuation property for (complex) germs definable in a certain o-minimal expansion of the real field and in order to study this question I propose notions of "complex Hardy fields" and "complex valuations".   Here, the value group is not necessarily ordered but, nevertheless, one can still prove a valuation inequality.

Workshop on Climate Change and Epidemics

Oxford-based organiser: Robin Thompson
Further Information

To sign up, please register your interest using this sign-up form by Thursday 30th November 2023 at the latest. Places will be confirmed by 5th December 2023. This workshop will take place at St Hilda's College, and is funded by the JUNIPER Consortium and Isaac Newton Institute.

Climate change is the key threat to this and future generations. With the Earth warming faster than ever before, we face inter-linked migration, infrastructure and public health challenges. In 2023, parts of Europe saw their hottest summer on record while other places have experienced unprecedented levels of rainfall and devastating floods. 

Many infectious diseases are climate-sensitive. For example, the locations and sizes of mosquito populations are linked to climate, which in turn affects the transmission of mosquito-borne diseases such as dengue and malaria. Therefore, changes in climate are altering the spatial and seasonal patterns of infections over time, putting millions of people at risk. In order to be more resilient to the health challenges posed by climate change, it is critical to understand its impacts on infectious diseases, both in the UK and globally.

The aim of this workshop is to bring together mathematical modellers, epidemiologists, climate scientists and public health specialists to identify key open challenges in our understanding of how climate change affects infectious diseases. The one-day workshop will consist of a series of talks and sessions covering the following themes:

  • Changes to infectious disease threats under a changing climate and regions most affected
  • Measures and initiatives to mitigate and build resilience in the UK and globally
  • Knowledge gaps that need to be filled to limit the impact of climate-sensitive infectious diseases
  • Challenges presented by climate-sensitive infectious diseases that provide opportunities to improve public health

The main aim of this event is to catalyse discussion between individuals in the research areas of climate science, infectious disease modelling and public health, fostering collaborations that address key challenges relating to climate-sensitive infectious diseases. Please note: this workshop is in-person only.
