[[Mathematics MOC]] # Linear algebra MOC Linear algebra is the study of [[Category of vector spaces]]. [[Vector notation in these notes]]. Linear algebra is generalized by [[Module theory MOC]]. ## Objects [[Vector space]] - [[Span]] - [[Linear (in)dependence]] - [[Vector basis]] - [[Dimension of a vector space]] ### Extra structure - [[Quadratic space]] ## Morphisms - [[Linear map]] ### In a fixed basis - [[Matrix algebra over a field]] - [[Types of square matrix]] - [[Row and column space]] ### Properties of morphisms - [[Eigenvectors, eigenvalues, and eigenspaces]] - [[Diagonalization]] ## Internal constructions - [[Vector subspace]] - [[Complement subspace]] ## Externally - [[Quotient vector space]] - [[Direct product vector space]] (product), [[Direct sum of vector spaces]] (coproduct) - [[Tensor product of vector spaces]] # --- #MOC | #state/develop | #SemBr
