AMCSAMCS 602-603. Algebraic Techniques for Applied Mathematics and Computational Science. Staff. First semester: We begin with an introduction to group theory. The emphasis is on groups as symmetries and transformations of space. After an introduction to abstract groups and the basic facts about finite groups, we turn our attention to compact Lie groups and their representations. In the latter connection we explore the connections between orthogonal polynomials, classical transcendental functions and group representations. This unit is completed with a discussion of finite groups and their applications in coding theory. Second semester: We turn to linear algebra and the structural properties of linear systems of equations relevant to their numerical solution. In this context we introduce eigenvalues and the spectral theory of matrices. Methods appropriate to the numerical solution of very large systems are discussed. We then turn to the problem of solving systems of polynomial equations, introducing basic properties of rings, ideals and modules. This allows us to define Grobner bases and their use in the numerical solution of algebraic equations. The theoretical content of this course is illustrated and supplemented throughout the year with substantial computational examples and assignments.

Through the Math and Statistics departments we also offer a one year course on Probability and Stochastic processes:
STAT 530-531/MATH 546-547. Probability, and Stochastic Processes for Applied Mathematics and Computational Science. Staff. Probability and statistics are the language most appropriate to the discussion of experimental data. This course introduces and places on a firm foundation, methods and ideas arising in probability theory and the theory of stochastic processes, and their applications to problems of empirical science. First semester: Basic concepts of measure theory, as measurement theory, probability theory, random variables, expectation, and independence, the weak and strong laws of large numbers, the central and Poisson limit theorems. Second semester: Measure theory revisited, conditional expectations, Martingales, Brownian motion, diffusion processes and stochastic integration and differential equations. Applications to the analysis of partial differential equations.
