1 VECTOR SPACES AND SUBSPACES What is a vector? Many are familiar with the concept of a vector as: • Something which has magnitude and direction. • an ordered pair or triple. • a description for quantities such as Force, velocity and acceleration. Such vectors belong to the foundation vector space - Rn - of all vector spaces. The. A vector space V over a ﬁeld K is said to be trivial if it consists of a single element (which must then be the zero element of V). A vector space with more than one element is said to be non-trivial. Examples of Vector Spaces Example. The set of all vectors in 3-dimensional Euclidean space is a real vector space: the vector. What is a Vector Space? Geo rey Scott These are informal notes designed to motivate the abstract de nition of a vector space to my MAT students. I had trouble understanding abstract vector spaces when I took linear algebra { I hope these help! Why we need vector spaces By now in your education, you’ve learned to solve problems like the one.

= the set of real sequences. (e)(Optional) C = a+ bi: a;b2R and i= p 1 = the set of complex numbers. REMARK: The rst four examples above will be our larger vector spaces. Whenever you have to show that a set is a vector space, ask yourself whether or not it is a subset of one of the above four vector spaces; if it is, then make use of the. A vector space V over a ﬁeld K is said to be trivial if it consists of a single element (which must then be the zero element of V). A vector space with more than one element is said to be non-trivial. Examples of Vector Spaces Example. The set of all vectors in 3-dimensional Euclidean space is a real vector space: the vector. 1 DEFINITION OF VECTOR SPACES 2 Vector spaces are very fundamental objects in mathematics. Deﬁnition 1 is an abstract deﬁnition, but there are many examples of vector spaces. You will see many examples of vector spaces throughout your mathematical life. Here are just a few: Example 1. Consider the set Fn of all n-tuples with elements in F. What is a Vector Space?

Such vectors belong to the foundation vector space - Rn - of all vector spaces. The. Vectors and Vector Spaces Vector Spaces Underlying every vector space (to be deﬁned shortly) is a scalar ﬁeld F. Examples of scalar ﬁelds are the real and the complex numbers R:= real numbers C:= complex numbers. These are the only ﬁelds we use here. Deﬁnition A vector space V is a collection of objects with a (vector).Vector space theory is concerned with two different kinds of mathematical ob- . The set of all real numbers is by far the most important example of a field. A vector space is a nonempty set V of objects, called vectors, on Example. Let M2×2 = {[ a b. c d. ]: a, b, c, d are real. } In this context, note that the 0 vector is. Example. 2. (1) R itself is a vector space;. (2) for any positive integer n, R n (i.e., the set of real n-ples) is a vector space;. (3) in general, if V is a vector space, V n. A (real) vector space V is a non-empty set equipped with an addition and a scalar . Example. • The set of all vectors in R. 3 with the third entry equal to 0. Example (a) The Euclidean space Rn is a vector space under the ordinary addition and scalar multiplication. (b) The set Pn of all polynomials of degree less . Such vectors belong to the foundation vector space - Rn - of all vector spaces. The . space of all real-valued functions (discussed in example 3 on page 5). Underlying every vector space (to be defined shortly) is a scalar field F. Examples of scalar fields are the real and the complex numbers . Example V is called a real vector space if F = R (field of real numbers), and a complex vector space EXAMPLE-1 Every field is a vector space over its any subfield. Reading assignment: Read [Textbook, Example , p. ] and study all .. The set R2 of all ordered pairs of real numers is a vector space over R. 3. The set . Note that rz ' z for any real number r. Example 1b leads us to believe that the commutative property for addi tion of vectors in three space carries over to E n.
