Office hours

I do not maintain regular office hours outside of term-time. However, I am still happy to meet with students by appointment. If you wish to see me, please drop me an email ( d.colquitt@liverpool.ac.uk) or tweet me (@danielcolquitt) to arrange an appointment.

Modules

This year I am teaching two modules

  • Math225: Vector calculus with applications in fluid mechanics
    This course provides an introduction to vector calculus including vector differential operators, vector integrals, and the associated theorems. We will also consider the applications of vector calculus to various physical systems including fluid mechanics and electromagnetism. More information can be found here.
  • Math206: Group project module
    This is an  undergraduate project based module. I currently offer two projects in Applied Mathematics
    • Further topics associated with ordinary differential equations.
      This is a project based on Math201 (Ordinary differential equations).
    • Further topics associated with vector calculus and related applications.
      This project is based on Math225 (Vector calculus with applications in fluid mechanics).

All the teaching materials associated with Math206 & Math225 are available to students on VITAL.

I am also developing a new module that will be delivered in September 2017:

  • Math430: Variational Calculus and its Applications
    In the same way that calculus is concerned with the extremisation of functions, variational calculus deals with the extremisation of functionals, or "functions of functions". Variational calculus underpins much of modern mathematical physics and applied mathematics. This module provides the fundamental background theory on variational calculus, which is accompanied by a range of physical examples.

    The course is delivered via thirty-six lectures and twelve tutorials. There will be weekly problem sheets, which will underpin your learning, enhance your understanding of the topics covered, and prepare you for the final examination. The final examination is worth 100% of your mark for this module.

Undergraduate Projects

I currently offer two undergraduate projects in Applied Mathematics, both of which are suitable for Math399, Math499, or Math490. A summary of the two projects is given below. For more information on undergraduate projects, please see this page.

Project One // PhoXonics: Wave propagation in periodic media

The study of wave propagation in periodic media underpins cutting edge research in a wide variety of fields including photonics, phononics, plasmonics, metamaterials, geophysics, solid-state physics, and non-desructive testing.

In this project we will examine various aspects of of wave propagation in periodic media, beginning with elementary one-dimensional problems. We will introduce Bloch-Floquet theory along with the concepts of Bloch waves, reciprocal space, Brillouin zones, group and phase velocity, dispersion, band structure, and resonances.

Initially, we will consider wave propagation in infinite domains. Time permitting, we will examine more advanced problems such as transmission problems for semi-infinite domains, higher dimensional systems, and multi-phase systems.

Students may find the content of the following modules useful, but not essential: Math224, Math323, Math324, and Math427. Some experience with MATLAB would also be useful.

Project Two // Elastodynamics: Waves in linearly elastic solids

In this project we will study the propagation of mechanical waves in elastic solids from first principles. Elastic waves in solids posses many interesting features that are not present in electromagnetism; such waves play a pivotal role in a range of fields from non-desructive testing, to seismology, and metamaterials.

We will begin by studying waves in simple one-dimensional structures such as strings, rods, and beams. We will derive the equations of motion from first principles and introduce the necessary elementary concepts of wave propagation. We will then move on to two-dimensional problems such as membranes and shells covering infinite, semi-infinite, and finite bodies.

Finally, we will consider wave propagation in three-dimensional elastic bodies. Time permitting, problems of scattering, diffraction, reflection and transmission will be studied, as well as external loading (e.g. line and point loads on elastic half-spaces).

Students may find the content of the following modules useful: Math224, Math225, Math243, Math323, Math324, Math427.
