DESCRIPTION - summary of the module content

This module focuses on vector spaces and linear systems, giving a rigorous treatment of algebraic techniques. The material of this module underpins several subsequent modules. Building on Vectors and Matrices, this module focuses on further in-depth studies of properties and characterization of vector spaces and manipulation of elements of vector spaces via linear maps, providing you with algebraic techniques, methodologies and some fundamental notions of modern algebra. Linear Algebra provides you with a solid base for your further studies, as it contributes to almost every field and topic within Mathematical Sciences.

This is a necessary foundation for subsequent modules in higher years, including Graphs, Networks and Algorithms, and Dynamical Systems and Control. Topics will include vector spaces, linear transformations, canonical forms and inner product spaces. The theoretical foundations will be complemented by a range of applied examples modelling technological and natural processes, crucially exploiting Linear Algebra to understand and enable these processes.


Prerequisite modules: “Calculus and Geometry” (ECM1901) and “Vector and Matrices” (ECM1902) or equivalent.

 

AIMS - intentions of the module

This module builds on “Vector and Matrices” (ECM1902). The aim is to advance and extend the concepts building on vectors and matrices, and to introduce theoretical foundations of algebraic theory. Algorithmic aspects and a rigorous theoretical development with proofs of theorems and methodology will be given equal importance.

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment. If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
