The Hirst Lecture and Society Meeting will comprise of two lectures. The first lecture, 'Maths and the city. A snapshot of numeracy in classical Athens,' will be given by Serafina Cuomo (Durham). The lecture will explore the various spaces and practices for Athenian numeracy in the 5th and 4th century BCE, and discuss rates of numeracy, and also sketch a profile of who may have been numerate at the time. The second lecture, 'Algebraic work with operations in China, 1st century—13th century' will be given by the Hirst Prize and Lectureship 2021 winner, Karine Chemla (CNRS & Université de Paris). This lecture will explore thirteenth-century Chinese mathematical works that attest to two interesting innovations: Qin Jiushao’s Mathematical Work in Nine Chapters (Shushu Jiuzhang 數書九章, 1247) describes an algorithm solving congruence equations in ways related to the so-called “Chinese remainder theorem”. Moreover, Li Ye’ 李冶 Measuring the Circle on the Sea-Mirror (Ceyuan haijing, 1248) shows how to use polynomial algebra to establish algebraic equations solving mathematical problems. Both authors make use of the same technical expression: “one establishes one heavenly source/origin as… li tian yuan yi wei...” Historians of the past have relied on modern interpretations of the texts to draw the conclusion that, in the two contexts, this expression had different technical meanings. Karine Chemla will be interpreting this expression in light of the ancient Chinese mathematical canon and its commentaries, an approach that allows us to give the same meaning to the expression and, more importantly, to bring to light a tradition of formal work on operations to which a series of Chinese mathematical documents attests. The event will be followed by a wine reception hosted at De Morgan House, and a Society dinner, at a nearby venue.

The meeting features the Hirst Lecture 2022, given by the winner of the Joint LMS-BSHM Hirst Prize and Lectureship 2021, Professor Karine Chemla (CNRS). There will also be an accompanying talk by Professor Serafina Cuomo (Durham). The Hirst Prize and Lectureship for the History of Mathematics is awarded for contributions to the study of the history of mathematics. The prize will be awarded in recognition of original and innovative work in the history of mathematics, which may be in any medium. This prize is awarded jointly by the LMS and the British Society for the History of Mathematics.

Inverse problems are widespread in many varied fields such as medical and satellite imaging, biology, astronomy, geophysics, environmental sciences, computer vision, energy, finance, and defence. These problems are inverse in the sense that they arise from seeking to use a mathematical or physical model “backwards” to indirectly determine a quantity of interest from the effect that this quantity causes on some observed data. A main challenge resulting from using models “backwards” to measure causes from their effects is that solutions are often not well posed, i.e., not unique and/or unstable with respect to small perturbations in the data. This difficulty has stimulated an important amount of research and innovation at the interface of applied mathematics, statistics, engineering, physics, and other fields, leading to great social and economic benefit through impact on science, medicine, and engineering.

The main aim of the Conference is to present new theoretical and methodological results and significant applications in Insurance and Finance by means of the capabilities of the interdisciplinary mathematical-statistical approach. The Steering Committee of the Conference would appreciate very much if you could collaborate in the success of the conference by participating in some activities such as the organization of sessions and/or the presentation of contributions (also through a co-author).

Sponsored by the ECM Committee of the Institute of Mathematics and its Applications (IMA). Feedback we received from our members is that networking and forming contacts with others at conferences is daunting but improves enjoyability of the conference. Forming contacts is what we want to facilitate at this event. This event is being run in a parallel format, we will host the event in Burleigh Court and run the same activities on Spatial.chat independently of each other. We will start the event with speeches on the history of the BAMC and ECMs, followed by what the ECM Committee does and information about the IMA. Then we will start the activities, which include: • Mathematical Taboo • Mathematical Headbandz • Celebrity Cameo • Group discussions on topics such as memorable moments during your PhD and your first conference experience

In this event, we will provide a safe environment for ECMs to discuss issues related to Equity, Diversity and Inclusion (EDI) with diversity champions of major mathematical societies and find out what those societies are doing on EDI matters, in particular focused on ECMs. We will begin the event with a talk on “Recognising the partners from the shadows: a whistle tour of the historical examples of compliance with social norms of exclusivity” from our very own Diversity Champion Snezana Lawrence. This will be followed by “connecting with the community”: using spatial.chat or zoom breakout rooms, TBC will each host a discussion based on issues of EDI in mathematics and for ECMs to generate conversation. Topics TBC. As well as these discussions, other ECM committees from the major mathematics societies will be there to answer questions on what they do.

The regional meeting on Monday 4 April 2022 will consists of three talks, by Professor Dame Frances Kirwan (Oxford), Professor Diane Maclagan (Warwick), and Professor Richard Thomas (Imperial College). The lectures are aimed at a general mathematical audience. All interested, whether LMS members or not, are most welcome to attend this event. This day meeting takes place during the LMS Workshop on Mirrors, Moduli and M-Theory in the Midlands from 4-7 April 2022.

Discrete mathematics is a branch of the mathematical sciences which poses a wide range of challenging research problems in its own right and gives rise to important applications in other fields. This 3rd IMA conference on discrete mathematics, following on from the previous two at Derby, will consider a range of aspects of discrete mathematics, both pure and applied. It is open to researchers working with mathematical structures and abstract constructs, and to those involved in the theory and practice of discrete mathematics. Results which establish links between different areas of discrete mathematics are welcomed, as are applications and the development of new tools. The purpose of this event is to highlight progress in the field through the development of novel theories, methodologies, and applications accordingly, and to inspire future work.

In the second edition of this School – which follows the 2021 online first edition – we aim to bring together experts from different communities to cover the investigation of diffusive systems from several viewpoints: analytically, combining methods and techniques from partial differential equations and dynamical systems to derive and analyse mathematical models for the applied phenomena; numerically, reviewing the most recent techniques and software for the computation of bifurcation diagrams and continuation with respect to the systems’ parameters; and, last but not least, from the applied - in particular biological – viewpoint, since a constant exchange of knowledge between the theoretical investigations and the experimental data is crucial in advancing research in this area.
