Colloquium – Sir Bernard Silverman, FRS, University of Oxford

Title: Science and Mathematics in Government: DNA Profiles, Border Security and Modern Slavery

Science and mathematics are relevant to a very wide range of Government policies and operations. For example, if someone is arrested but not charged, for how long should their DNA profile be retained? How should resources be allocated to queues at the border? How many victims of modern slavery and human trafficking are there in the UK today? Professor Silverman will discuss these and other aspects of his work as Chief Scientific Adviser to the Home Office, and will reflect more broadly on issues around the contribution of science to public policy.

The talk will be held from 4.30pm in Frank Lecture Theatre (G44), Physics, and will be followed by a drinks reception in the Maths common room.

One two many: why is 3 so much bigger than 2?

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!

 

The talk will be held in Mott Lecture Theatre, Physics, from 6pm – 7pm.

Colloquium – Prof. Jim Davis, University of Richmond

Due to today’s weather conditions this talk has been cancelled. Apologies for any inconvenience caused.

Title: Apple vs. Samsung. A mathematical battle

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.

 

The talk will be held from 4.30pm in Powell Lecture Theatre, Physics, and will be followed by a drinks reception in the Maths common room.

Heilbronn Colloquium

Henry Cohn, Microsoft

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).

16.00 20th February 2018

SM1, Main Building, University of Bristol

Title to be announced. The colloquium will be followed by a wine reception in the Common Room at the Main Maths Building.

How to Win a Million Dollars – Sophie Stevens

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…

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!

The talk will be held in Mott Lecture Theatre, Physics, from 6pm – 7pm.

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.
