MA26610 Multilinear Algebra
Introductory description
It is a second Linear Algebra module, where advanced linear algebra concepts are rigorously developed for students familiar with algebraic tools.
Module aims
It will continue the study of linear algebra, which was begun in Year 1, having benefited from students finishing Abstract Algebra (Algebra3 or Groups and Rings) in term 1.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
Liner maps: Jordan Normal form, CayleyHamilton theorem, primary decomposition, functions of matrices
Quadratic forms over R and C: orthonormal basis, GramSchmidt process, diagonalisation, singular value decomposition, hermitian forms and normal matrices
Tensors: tensor product of vector spaces as a quotient of the free vector space, universal mapping property, its basis, (n,k)tensor on a vector space, change of basis
Further topics: dual space, dual linear map, bilinear forms, skewsymmetric forms, determinant, Darboux Theorem, Witt Extension Theorem, free associative algebra and tensor algebra, other algebras (exterior, symmetric, Clifford).
Learning outcomes
By the end of the module, students should be able to:
 develop full command of the theory and computation of the the Jordan canonical form of matrices and linear maps
 learn how to define and to compute functions of matrices
 develop the working knowledge of bilinear forms and quadratic forms
 master the concept of tensor and get proficient manipulating tensors

Subject specific skills
This module teaches students to carry out fundamental calculations with matrices, including the theory and computation of the Jordan canonical form of matrices and linear maps; bilinear forms, diagonalizing quadratic forms, and choosing canonical bases for these. After that the module introduces the notion of tensor, treating them rigorously.
Transferable skills
The algorithmic techniques taught have widespread "real world" applications. Examples include ranking in search engines, linear programming and optimisation, signal analysis, and graphics. To also include: clear and precise thinking; the ability to follow complex reasoning; constructing logical arguments, and exposing illogical ones; and formulating problems as algorithms, thereby enhancing understanding of details and rendering them suitable for computer implementation.
