Linear Algebra ​

This section covers essential linear algebra concepts for quantitative finance.

Topics Covered ​

  • Vectors and Vector Spaces
  • Matrices and Matrix Operations
  • Eigenvalues and Eigenvectors
  • Matrix Decompositions
  • Applications in Finance

Vector Spaces ​

A vector space is a collection of objects called vectors that can be added together and multiplied by scalars.

Matrix Operations ​

Basic Operations ​

Matrix addition, subtraction, and multiplication form the foundation of linear algebra.

Determinants ​

The determinant of a matrix provides important information about the matrix properties.

Eigenvalues and Eigenvectors ​

For a square matrix A, an eigenvector v and eigenvalue λ satisfy:

Av=λv

These concepts are crucial in:

  • Principal Component Analysis (PCA)
  • Risk modeling
  • Portfolio optimization

Applications in Finance ​

Linear algebra is extensively used in:

  • Portfolio theory
  • Factor models
  • Risk management
  • Options pricing models
