All over mathematics there are examples where changing a 2 to a 3 turns a doable problem into a completely unmanageable one. What on earth is going on?
This talk forms part of the Matrix series of evening talks, designed to show off bits of maths that you won’t see in lectures – no special knowledge required!
Apple and Samsung have been fighting patent battles around the world. Come learn about the mathematics at the heart of one of these battles, the error correcting codes used in 3G communication. We will give a gentle introduction to coding theory, explain why this caused a legal battle, and we will conclude by describing why President Obama ultimately vetoed the ruling by the court (the first time a president had used that veto power in nearly 30 years!). Also, come to find out how Bristol played a crucial role in this story.
This is a one day meeting in Bristol about rational points, featuring talks by Ulrich Derenthal and Nils Bruin, organised by Tim Browning and Adelina Mânzateanu.
This is the seventh 1-day meeting in additive combinatorics and analytic number theory and will take place at the University of Bristol. The event is funded by an LMS Scheme 3 Grant (31623) and the School of Mathematics at the University of Bristol.

The sphere packing problem in dimensions 8 and 24
What is the densest packing of congruent spheres in Euclidean space? This problem arises naturally in geometry, number theory, and information theory, but it is notoriously difficult to solve, and until recently no sharp bounds were known above three dimensions. In 2016 Maryna Viazovska found a remarkable solution of the sphere packing problem in eight dimensions. In this talk I’ll describe how her breakthrough works and where it comes from, as well as follow-up work extending it to twenty-four dimensions (joint work with Kumar, Miller, Radchenko, and Viazovska).

Some problems are easy. Some problems are hard. Some problems seem so hard that they’ve got a bounty to their name. One such problem is a meta-problem: a problem about problems. Or, to give it a name, P vs NP: are problems really as hard as we think they are? If so, what does this mean for maths, computing and even humanity itself? This talk will introduce and explain the problem, hardness and complexity theory. And who knows, maybe you’ll even win a million dollars…

Title and abstract for Colloquium:
Wavelets, with Image processing applications for Art History
Wavelets are the building blocks for mathematical tool that emerged in
the 1980s as an interesting way to decompose, understand and compute
with signals, data and operators. The talk will review the basics of
wavelets and their mathematical properties; in a second part, we will
visit some recent applications of wavelets and image processing to
help understand art works, their manufacture process and their state of
conservation.
