Topics discussed include the definition of a finite dimensional vector space, the proof that. A smooth surface without any thickness is a two dimensional object.
I would not recommend the present book for a first course in linear algebra for any audience, not even math majors, but it is a good choice for a second course. Let xbe a nite dimensional vector space over r or c and fb 1b nga basis for x. Roughly speaking, the dimension of a vector space should describe the number of degrees of freedom an inhabitant of the space has. The techniques taught are meant to be generalizable to the infinite dimensional cases i. The book brought him instant fame as an expositor of mathematics.

It follows that, and thus has a unique multiplicative inverse. Finitedimensional vector spaces by paul halmos is a classic of linear algebra. Now, r is certainly a vector space over q however, it cannot have a finite basis, because of the reasons you mentioned r is simply too large. In general, compact sets in normed vector spaces are necessarily closed and bounded. Finite dimensional spaces notes from the functional analysis course fall 07 spring 08 convention. So its perfectly conceivable that there are infinite vector spaces over even finite fields, and in fact this is possible. Well, in my previous linear algebra courses we mostly worked with finitedimensional vector spaces, so in my mind i started to consider all vector spaces finitedimensional. Second edition dover books on mathematics 2 reprint by paul r. Linear algebra focuses not on arbitrary vector spaces, but on.
The idea is to emphasize the simple geometric notions common to many parts of mathematics and its applications, and to do so in a language that gives away the trade secrets and tells the student what is in the back of the minds of people proving theorems about.
