Description
This module will enable the student to build on the knowledge and skills developed in
PHY1026
in order to achieve a deeper understanding of and greater competence in some central
mathematical ideas and techniques used throughout physics. The emphasis is on practical
skills rather than formal proofs. Students will acquire skills in some key techniques that
relate directly to the advanced modules they will meet in the later stages of their degree
programme, but also have wide applicability across the mathematical sciences.
Module Aims
This module predates the current template; refer to the description above and the following ILO sections.

Solution of linear partial differential equations
 Simple second order differential equations and common varieties: Harmonic oscillator, Schrödinger equation, Poisson's equation, wave equation and diffusion equation.
 Separation of variables: The Laplacian family of equations in physics, separation of variables, mechanics of the technique, form of solutions, general solutions in series form, relation to Fourier series, spatial boundary conditions, time dependence, initial conditions.
 Examples: rectangular drum, classical and quantum harmonic oscillator, waves at a boundary, temperature distributions, wavepacket/quantum particle in a box
 Role of symmetry: Cylindrical and spherical polar coordinates, appearance of special functions. Use of special functions by analogy to sin, cos, sinh, cosh etc.
 Examples: circular drum, hydrogen wave function

Linear Algebra
 Revision: Row and column vectors, matrices, matrix algebra, the solutions of systems of linear equations.
 Eigenvalue equations I: The matrix equation Ax=ax, solving the matrix equation, the secular determinant, eigenvalues and eigenvectors, canonical form, normal modes/harmonics, simple coupled oscillators.
 Eigenvalue equations II: Properties of eigenvectors: orthogonality, degeneracy, as basis vectors.
 Eigenvalue equations III: Differential equations as eigenvalue equations and the matrix representation Ax=ax; choosing the basis, solving the equation, the secular determinant, eigenvalues and eigenvectors.
 Examples: classical coupled modes, Schrödinger wave equation
 Approximate solutions to differential equations (perturbation theory): use of eigenvectors, first and secondorder through repeated substitution, problem of degeneracies.
 Examples: quantum particle in a well, a mass on drum, coupled particles
