#### Summary

The purpose of this course is to introduce the basic notions of linear algebra and to prove rigorously the main results of the subject.

#### Content

- Linear forms, dual space, bilinear forms, sesquilinear forms, symmetric and hermitian matrices, Sylvester's theorem.

- Inner products: orthonormal bases, orthogonal projections, orthogonal and unitary matrices.

- Systems of linear differential equations with constant coefficients.

-Basics of multilinear algebra

#### Keywords

inner product, bilinearity, orthogonality, scalar product, spectral theorem

Linear algebra I

#### Learning Outcomes

By the end of the course, the student must be able to:
• Give an example to illustrate the basic concepts of the course
• State all definitions and theorems from the course
• Reconstruct proofs from the course
• Apply techniques from the course to various problems in mathematics and physics
• Compute basechange for linear maps, bilinear forms, sesquilinear forms; Gram matrix of a bilinear or sesquilinear form, Sylvester basis for a symmetric form, orthonormal basis for a given symmetric or symplectic form, orthogonal projection on a vector subspace, singular values of a linear map, Jordan normal form of a matrix, exponential of a matrix.
• Formulate main ideas of the course
• Synthesize major results of the course to give a `big picture' of the material and its potential applications
• Create new proof of correct statements in linear algebra
• Design counterexamples for wrong statements in linear algebra

#### Transversal skills

• Use a work methodology appropriate to the task.
• Assess one's own level of skill acquisition, and plan their on-going learning goals.
• Continue to work through difficulties or initial failure to find optimal solutions.
• Access and evaluate appropriate sources of information.
