This book begins by developing a conceptual framework for the topic using the central objects, vector spaces and linear transformations. It covers the same concepts, skills, and, applications as conventional Linear Algebra texts in a one-semester course, but students walk away with a much richer ...
Key notes: The nullspace N(A) in RnRn contains all solutions x to Ax=0Ax=0. This includes x=0. Elimination (from A to U to R) does not change the nullspace : N(A)=N(U)=N(R). The reduced row echelon form R=rref(A) has all pivots = 1, with zeros above and below. If...
1.1.1 Vector Spaces You should already be familiar with vector spaces from linear algebra. Informally a vector space is a collection of objects called vectors that can be added and subtracted as well as multiplied by constants. Vectors are often represented geometrically by arrows. These arrows ar...
In these notes I will discuss two approaches to the study of the orbits, invariants, etc, of a linear reductive group G operating on a finite dimensional vector space V. The two techniques are the "quiver method" and the "slice method", which are discussed in Chapters I and II ...

The equality LE∘LE′(X)=X2n+X implies that LE′(F2n) is included in E and this completes the proof since these two vector spaces have the same dimension by the fundamental theorem of linear algebra. Note that this then proves that LE′ and LE commutate (which is not straightforward ...
