MATH10120 Linear Algebra with Applications to Economics

Academic Year 2020/2021

This course offers a first introduction to linear algebra, and is tailored to meet the needs of students in Economics & Finance. During the course of this module students will be introduced to matrix algebra, the Gauss-Jordan algorithm, methods of computing eigenvalues and eigenvectors of a matrix, the theory of determinants, properties of real vector spaces. Applications of these topics to economics are described at regular intervals and given as motivation for their study. These include Leontief input/output models and Markov chains.
