Heilbronn Colloquium – Prof. Marta Casanellas, UPC Universitat Politècnica de Catalunya
Title: From phylogenetics to algebraic geometry
Abstract: Many of the evolutionary models used in phylogenetics can be viewed as algebraic varieties. In this expository talk we will explain the main goals of phylogenetics, introduce evolutionary Markov models on trees, and show how algebraic varieties arise in this context. Moreover, we will see how an in-depth geometric study of these varieties leads to improvements on phylogenetic reconstruction methods. We shall illustrate these improvements by showing results on simulated and real data and by comparing them to widely used methods in phylogenetics.
Further information
The colloquium will take place in Mott Lecturer Theatre in the Physics Building at 16.00-17:00 on Wednesday 12th December. It will be followed by a drinks reception in the Maths Common Room.

Graduate student lecture: Random matrices in wireless communication systems
Benjamin Meaker visiting Professor: Peter Smith Date: 23 July 2018 Time: 2pm Location: Howard House, Level 4 Seminar Room This talk will outline the many applications of random matrices in communications. In particular, modern cellular systems where base stations communicate with many mobile users with smart phones are discussed. The modelling, design and analysis of […]
Departmental lecture: Asymptotics of large communication systems
Benjamin Meaker visiting Professor: Peter Smith Date: 26 July 2018 Time: 2pm Location: Howard House, Level 4 Seminar Room Large wireless communication networks are widely believed to offer “free” interference reduction. This has led to a huge growth of research in performance analysis of large systems, where many users communicate with 100s of antennas located […]
Open lecture: Smart phones and statistics – where is the connection?
Benjamin Meaker visiting Professor: Peter Smith Date: 18 July 2018 Time: 2pm Location: Howard House, Level 4 Seminar Room Although we take them for granted, mobile devices such as smart phones are small miracles of engineering and electronics. These devices are constantly evolving and fundamental research and long term planning is always running in parallel […]
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.

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).
