Key Concepts

Linear Transformation

A linear transformation is a mapping between vector spaces that preserves both vector addition and scalar multiplication. It is typically represented by a matrix when dealing with finite-dimensional spaces, which allows for a compact and concrete expression of the transformation process.

Matrix Representation

A matrix provides a way to represent a linear transformation as a systematic rule of assignment from one vector space to another. Multiplying a vector by a matrix leads to an output vector, encapsulating the transformation process in algebraic terms.

Kernel (Null Space)

The kernel of a linear transformation is the collection of all vectors from the domain that are mapped to the zero vector in the codomain. It is found by solving the homogeneous equation associated with the transformation and reveals important information about the injectivity of the transformation.

Image (Range)

The image or range of a linear transformation consists of all the vectors in the codomain that can be obtained as outputs of the transformation. It illustrates the span of the transformation and is crucial for understanding the dimensions and potential limitations of the mapping.

Systems of Linear Equations

Solving systems of linear equations is essential when determining both the kernel and the particular solutions corresponding to a given vector in the codomain. Methods to solve these systems, such as substitution or row reduction, allow one to determine the structure of the solution set, which can either be a subspace or an affine subset of the domain.
