Colloquium – Proffessor Delaram Kahrobaei, University of York

Title: Interactions between Group Theory, Cyber Security, Artificial Intelligence and Quantum Computation

Abstract:

In this talk, I explore how group theory plays a crucial role in data science and artificial intelligence as well as cyber security and quantum computation; at the same time, computer science and machine learning could help group theorists tackle some of their open problems. A second theme of the talk will be to formulate graph theoretic problems associated with computational complexity as group theoretic questions pertaining to graph groups. Lastly, we will look at the question of whether certain group-based cryptographic schemes are quantum-safe.

Brief bio:

Professor Delaram Kahrobaei holds the Chair of Cyber Security at the University of York. Prior to that, she was a Full Professor at the City University of New York. She is President and co-founder of the start-up, Infoshield Inc., and director of the York Interdisciplinary Centre for Cyber Security Research. She is an Associate Editor of Advances of Mathematics of Communication, and Chief Editor of the International Journal of Computer Mathematics: Computer Systems Theory. Her main research areas are Post-Quantum Algebraic Cryptography, Information Security, Data Science and Applied Algebra.

Heilbronn Colloquium – Maynard

16th December 2019

University of Bristol

We are very pleased to welcome James Maynard to the University of Bristol for a Heilbronn colloquium.

James is primarily interested in classical number theory, in particular the distribution of prime numbers. His research focuses on using tools from analytic number theory, particularly sieve methods, to study primes.

Title:  Approximating reals by fractions

Abstract: How well can you approximate real numbers by fractions with denominators coming from a given set? Although this old question has applications in many areas, in general this question seems impossibly hard – we don’t even know whether e+pi is rational or not!
If you allow for a tiny number of bad exceptions, then a beautiful dichotomy occurs – either almost everything can be approximated or almost nothing! I’ll talk about this problem and recent joint work with Dimitris Koukoulopoulos which classifies when these options occur, answering an old question of Duffin and Schaeffer. This relies on a fun blend of different ideas, including ergodic theory, analytic number theory and graph theory.

The colloquium will take place in Lecture theatre 2.41, Fry Building at 16:00- 17:00 on Monday 16th December followed by a wine reception in the Fry Common room. To help us plan catering, please complete the short registration form if you are planning to attend the colloquium.

Colloquium – Peter Landrock, Cryptomathic

Title: The mathematics behind digital signatures

Public Key Cryptography as we use it, with billions of transactions being executed every day, was first developed respectively 50 years ago in the case of RSA and modular exponentiation, and 35 years ago in the case of elliptic curves. If quantum computers are developed at a sufficiently advanced level, currently used methods will no longer be considered secure due to Schor’s algorithm.

But the mathematics behind them remains fascinating and is connected to several interesting questions and conjectures in number theory, which is the main focus of the talk. Topics will include short orbits for the discrete logarithm map, and properties of primes that are congruent to 1 modulo 4.


Further information

The talk will be held in the Fry Building, room 2.41, from 4pm – 5pm and will be followed by a drinks reception in the Maths common room.

The event is open to University of Bristol staff and students, as well as the general public.

We also invite you to join us for the plenary talks which showcase a wide range of mathematics happening in the UK right now.

Whether you are in the first or final year of your PhD, this is the conference for you.


How to register

Further information about the conference, including the full schedule and how you can register will be made available soon through the official website. Please check back here for further updates.

Women and Non-Binary People in Mathematics: Opportunities for the Future 2019

Join us for our annual Women and Non-Binary People in Mathematics event, Tuesday 5th and Wednesday 6th November 2019 – open to female and non-binary students in the UK and Ireland.

A PhD in mathematics can offer you independence, challenging problems and an inspiring job, as well as the chance to travel and the opportunity to make a difference.

This two-day event is aimed at encouraging women and non-binary people to consider continuing their studies to PhD level.

The event features talks from mathematicians working both in universities and industry, giving insight into their current roles and their careers to date. Even more importantly, there is ample time to talk in small groups to the other participants who are facing the same decisions, and to current PhD students who have recently faced the same questions. It will be an opportunity to discuss your motivations as well as your concerns, and specifically to identify and seek to address any concerns related to gender identity.

The Wednesday afternoon session is open to all students and will more broadly address the nature of PhD research, the work environment, the application process, and career options. It will also provide an opportunity to discuss issues and concerns around PhD study.

How to apply

Please note that registration for this year’s event is now closed.

Heilbronn Colloquium Rudnick

5th September 2019

University of Bristol

We are delighted to welcome Zeev Rudnick (Tel Aviv University), to the University of Bristol for a Heilbronn Colloquium.

Zeev is a Professor of Mathematics at Tel-Aviv University, where he holds the Cissie and Aaron Beare Chair in Number Theory. His main interests are in number theory, mathematical physics and quantum chaos, and his world-leading research in these fields has attracted numerous awards and prizes. For example, in 2001 he received the Erdos Prize of the Israel Mathematical Union and he was elected a Fellow of the American Mathematical Society in 2012. He was an invited speaker at the International Congress of Mathematicians in 2014 and his current research is supported by an ERC Advanced Grant. 

Title: Quantum chaos, eigenvalue statistics and the Fibonacci sequence

Abstract:
One of the outstanding insights in the field of “Quantum Chaos” is a conjectural description of local statistics of the energy levels of simple quantum systems according to crude properties of the dynamics of classical limit, such as integrability, where one expects Poisson statistics, versus chaotic dynamics, where one expects Random Matrix Theory statistics. These insights were obtained by physicists in the last quarter of the 20-th century (much of it in Bristol!). However, mathematicians are far behind in understanding the scope and validity of this theory. The first part of the lecture will be dedicated to an introduction to these conjectures, which I believe deserve to be better known in the mathematics community. In the second part, I will describe more recent work on statistics of the minimal gap between the first N eigenvalues for one such simple integrable system, a rectangular billiard having irrational squared aspect ratio. When the aspect ratio is the “golden ratio”, the problem involves some curious and entertaining properties of the Fibonacci sequence.

The colloquium will take place in 1.15 in the Queens Building at 16.00 on Thursday 5th September. It will be followed by a wine reception in the Pugsley Foyer. To help us plan space and catering, please complete the short registration form if you are planning to come.
