Lecture

Vector Spaces and Linear Applications

Description

This lecture introduces vector spaces as non-empty sets with defined addition and scalar multiplication operations satisfying ten axioms. It covers examples of vector spaces with usual addition and scalar multiplication in R^2, matrices, and polynomials. The concept of subspaces is explained, along with the properties of subspaces and their verification. The lecture also discusses the kernel and image of a matrix, as well as the reduced row-echelon form and solutions of linear systems. It concludes with the concepts of linear independence, bases, and the differences between the kernel and image of a matrix.
