Orthogonal Decomposition Theorem Part 1: Defining the Orthogonal Complement
Description: Given a subspace, we define W perp as the subspace of vectors orthogonal to everything in W. This property turns out to be equivalent to only demanding orthogonality to all basis vectors in W. Learning Objectives: 1) Given a subspace, compute its orthogonal compliment. Th

In this video, I define the concept of orthogonal projection of a vector on a line (and on more general subspaces), derive a very nice formula for it, and show why orthogonal projections are so useful. You might even see the hugging formula again. Enjoy! This is the second part of the ort

A complementation proves useful to separate divergent terms from convergent terms. Hence the relevance of complementation in the context of renormalisation. The very notion of separation is furthermore related to that of locality. We extend the correspondence between Euclidean structures o

Spectral Theorem for Real Matrices: General nxn Case
Linear Algebra: We state and prove the Spectral Theorem for real vector spaces. That is, if A is a real nxn symmetric matrix, we show that A can be diagonalized using an orthogonal matrix. The proof refers to the 2x2 case and to results from the video Beyond Eigenspaces: Real Invariant
