Advanced Linear Algebra, Lecture 1.1: Vector spaces and linearity

The fundamental objects in linear algebra are vector spaces, which consist of a X of vectors closed under addition, subtraction, and scalar multiplication from a field K. Linear maps are structure preserving functions between vector spaces. In this lecture, we see the formal definitions and some examples of vector spaces and subspaces.

It’s time for me, an incoming senior physics student, to teach myself and be ready for quantum physics. I didn’t and I won’t take undergraduate level linear algebra. It’s not required for my physics major, and it might be too “easy”. I’m so glad that I found your channel! This is exactly I need to learn in this summer! ❤❤❤❤

I really wish you would upload videos on abstract algebra 2. it would be a life saver

A(v+w) is not equal to Av + Bw unless B = A, on 24'.

29:58 Does the function f satisfies f(x1)=a1, ..., f(xn)=an simultaneously?
How can describe set of basis in case of (iii)?
Thanks a lot!

Prof. Macauley is a genius (and a lowkey badass).

Thank you, professor! I am searching for such a video. Your visual group theory series is awesome, and I wanted to have group theory of vector space. Definitely, I will continue this course. Thank you!

Thank you! Can I see your presentation slides as your visual group theory?

Why the dual notation for the field, using both F and K?

You stated that Z is not a Field because 0 does not have a multiplicative inverse. But, under Field, you said only that F\{0} must be an abelian group. The only thing you said requires a multiplicative inverse is a Group. You did not say that a Field must meet all the requirements of a Group.
