MAT1120 – Linear algebra

Choose semester

Course content

MAT1120 gives a thorough introduction to linear algebra with emphasis on vector spaces, linear maps, spectral theory, orthogonality and applications of this theory. MATLAB is used for illustrations and for solving numerically various problems. MAT1120 is based on, and is a natural continuation of, MAT1110, and the course is a building block for a number of advanced mathematical courses.

Learning outcome

After completing the course you:

• have applied basic theory for linear systems of equations;
• are well acquainted with the definition of general vector spaces, and with important examples of these spaces, such as the usual n-dimensional Euclidean space and different function spaces;
• master concepts like subspace and linear independence, and are  familiar with natural subspaces associated with matrices;
• have a good understanding of the notions of basis and dimension of vector spaces, are accustomed with change of basis and can use coordinate vectors to solve different problems;
• are able to find the matrix representation of linear maps relative to different bases;
• know the theory of eigenvalues and eigenvectors, and can use this to solve certain systems of differential equations and analyze discrete dynamical systems;
• are familiar with inner product spaces, orthogonality and orthogonal projections, and can compute orthogonal bases;
• can solve least-squares problems, and apply this to linear models;
• know the spectral theorem for symmetric matrices, and can analyze quadratic forms;
• can compute the singular value decomposition of a matrix, and know how to use the information it provides;
• can solve different linear algebra problems numerically, for instance how to approximate eigenvalues.

Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

Prerequisites

Formal prerequisite knowledge

In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:

• Mathematics R1 (or Mathematics S1 and S2) + R2

And and in addition one of these:

• Physics (1+2)
• Chemistry (1+2)

The special admission requirements may also be covered by equivalent studies from Norwegian upper secondary school or by other equivalent studies (in Norwegian).

Overlapping courses

10 credits with MAT120. 9 credits against MA103. 10 credits against MA104. 6 credits against MA113. 10 credits against MA114.

Teaching

4 hours of lectures and 2 hours of problem solving in plenum per week. In addition there will be exercise solving groups during the week, with guidance available.

The number of groups offered can be adjusted during the semester, depending on attendance.
