There's a widespread belief that people who are good at maths can go into finance and become obscenely rich. This talk tries to put that in perspective by describing a common approach to algorithmic trading, and exploring some of the reasons why it's harder than it sounds.

Fluid models are widely employed in many fields of science, ranging from astronomy and physics to biology and chemistry. The fundamental principle, and motivation, behind fluid models is to provide an effective macroscopic representation of the collective behaviour arising from a large number of (...)

Despite Statistics being the traditional field for data analysis, people with formal statistical training form a relatively small segment of the Data Science community. Indeed, it is easy to conclude that the influence of Statistics on the field is waning: for instance, Python is slightly more (...)

Title: Derangement action digraphs and graphs

Time and place: Fri 04 May, 2018 in Weatherburn LT

Abstract: Derangement action digraphs are closely related to group action digraphs, which were introduced by Annexstein, Baumslag and (...)

Title: A cycle of maximum order in a graph of high minimum degree has a chord

Time and place: 4pm 11 May 2018, Weatherburn LT

Abstract: A long standing conjecture of Thomassen states that every cycle of (...)

Abstract: There is a striking connection between the zeroes of the Riemann zeta-function and the distribution of the primes. In this talk I shall mention some analytic properties of the zeta-function that when known explicitly enable one to estimate, very accurately, the size of the n-th prime (...)

Abstract: This seminar is in the (very) occasional CMSC Technical Seminar Series covering useful (...)

Graphs (also called networks) with a high degree of symmetry are particularly nice objects to study mathematically. When studying the symmetries of a graph it is often useful to look at the local symmetries, that is, those that fix a particular vertex.  An important question then becomes whether (...)
