Switches in Biological and Physical Computation

Abstract

Switches are ubiquitous in both physical and biological circuits and play a pivotal role in their exquisite behaviour. We will discuss chemical “switches” in two separate scenarios: chemical reaction networks, and synthetic biology.

Dr. Christopher Townsend – 10/01/2018 at 3:30 pm - 4:30 pm in W152

Cryptocurrency, Blockchain and the Financial Markets

The seminar will give an overview of how blockchain based crypto-currencies such as Bitcoin work and describe some of the financial landscape in which they operate.

Dr. Ben Fairbairn (Birkbeck) – 06/12/2017 at 3:30 pm - 4:30 pm in WG48

Invertible Generating Graphs

Let G be a group. Recall that the generating graph of G is defined as follows: the vertices are the non-trivial elements of G with two vertices x and y being adjoined by an edge if and only if the pair x and y generate G. This much-studied object encodes many of the quantities studied for measuring how easily generating pairs can be found. In this talk we discuss a variant of the generating graph recently introduced by the speaker.

Dr. Nick Sharples (Middlesex) – 22/11/2017 at 3:30 pm - 4:30 pm in WG48

Non-uniqueness of differential equations

Differential equations are an important tool in modelling many phenomena in the real world. However, these mathematical abstractions may exhibit behaviours that are not physically reasonable, such has admitting multiple solutions for a given initial condition, raising questions their validity as models.

In this gentle talk I will discuss the issues of non-uniqueness of Ordinary and Partial Differential Equations in several frameworks, and some recent work to establish uniqueness for differential equations with sufficiently regular coefficients.

Dr. Jonathan Elmer (Middlesex) – 08/11/2017 at 3:30 pm - 4:30 pm in WG50

Modular coinvariants

The algebra of coinvariants of a finite group G acting on V is the quotient of the algebra of invariants k[V]^G by the ideal of k[V] generated by positive degree invariants. Unlike the algebra of invariants itself, it is fairly computable. The algebra of coinvariants sometimes contains information about the structure of the invariants. Like many things in invariant theory and representation theory, more is known in the non-modular case (where |G| is not divisible by the characteristic of K) than in the modular case. I will report on some recent work with Mufit Sezer which aims to understand more about coinvariants in the modular case.

Feynman path integrals and quantum anomalies.

Invariant Theory: Recent Progress and Applications – 16/06/2017 at 12:00 pm - 6:00 pm in The Quad

A one day meeting in *invariant theory: recent progress and applications *will take place on Friday 16th June at Middlesex University, Hendon. The meeting aims to bring together researchers in invariant theory and researchers in other areas of algebra and geometry in which invariant theory can be applied. The following have agreed to speak:

- Emilie Dufresne (Nottingham)
- Jonathan Elmer (Middlesex)
- R. J. Shank (Kent)

There is a limited amount of funding available to cover travel and accommodation expenses for PhD students. For further information, send me an email on j.elmer at mdx dot ac dot uk. The meeting is supported by an LMS scheme 1 (celebrating new appointments) grant.

There is no registration fee, but places are limited. To book your place, please use the form below.

Topologies and their specialization pre-orders

Pre-orders play an important role in economics as preference relations and in cosmology as causality relation.

In this talk, we shall consider several properties of pre-orders and their corresponding topological properties, such as compactness, connectedness, countability, Baire category theorem and some others.

Dr. Emilie Dufresne (Durham) – 08/02/2017 at 3:00 pm - 4:00 pm in VG02

The geometry of sloppiness

Mathematical models in the sciences often require the estimation of unknown parameter values from data. Sloppiness provides information about the uncertainty of this task. We develop a precise mathematical foundation for sloppiness and define rigorously its key concepts.

We illustrate the various concepts involved in the proper definition of sloppiness with examples of ordinary differential equation models with time series data.

We also highlight the links with invariant theory and the notion of separating set.
