The course contains 38 short lecture videos, with a few problems to solve after each lecture. So with this chapter of lang you are moving ahead hundreds of years from newton and leibnitz, perhaps 70 years from riemann. A vector space over a eld kis a set v which has two basic operations, addition and scalar multiplication, satisfying certain requirements. In this monograph we make the standing assumption that all vector spaces use either the real or the complex numbers as scalars, and we say real vector spaces and complex vector spaces to specify whether real or complex numbers are being used. The equality is due to vector space properties of v. Why we need vector spaces by now in your education, youve learned to solve problems like the one.
