Stephen Andrilli, David Hecker, in Elementary Linear Algebra (Sixth Edition), 2023 Definition of a Vector Space We now introduce a general class of sets called vector spaces,1 with operations of addition and scalar multiplication having the same eight properties from Theorems 1.3 and 1.12, as we...
Finite Dimensional Vector Spaces Stephen Andrilli, David Hecker, in Elementary Linear Algebra (Fourth Edition), 2010 Publisher Summary This chapter establishes many important results related to the vector spaces. It also introduces the general class of sets called “vector spaces” that can be defined...
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 ...

Additive Identity and Vector Spaces The additive identity property has applications outside of simply adding 0 to any number. Invector spaces, the additive identity is defined as follows: There exists an element Θ∈ V such that 0 + v = v for all v ∈ V; ...

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...
