1 Solutions to the Exercises on Linear Algebra 1. What is the most general function of three Grassmann numbers θ1, θ2, θ3? Solution: Grassmann numbers anticommute, that is {θi,θj }= θiθj +θj θi = 0 and θ 2 = θ 2 = θ 2 = 0. So the most general function of three Grassmann numbers is f (θ1, θ2, θ3) = a + b θ1 + c θ2 + d θ3 + e θ1θ2 + f θ1θ3 + g θ2θ3 + h θ1θ2θ3. 2. Derive the cyclicity (1.24) of the trace from Eq.(1.23). Solution: Since Tr(AB) = Tr(B A), it follo...

This document clearly describes, with detailed notes and examples, how to evaluate/solve the following: ~ Dot products and Orthonormal Bases ~ Unitary and Hermitian Matrices ~ Fourier series as taught by the University of the Witwatersrand. As a student, I am always searching for a great set of notes that I can rely on to ensure that I can achieve the best of my abilities. With this colour coded document, a second year can utilise their time more efficiently to practice more, instead of ...

Full Cheat Sheet for Partial Differential Equations and Advanced Linear Algebra. Very useful for people who are learning PDEs in general, but especially tailored to MATH 271 Students at McGill. The cheat sheet has extra pages where zoomed in sections of the cheat sheet are shown so you can read the things clearly. 1. Partial Differential Equations The derivations of the fundamental partial differential equations governing engineering systems: fluid flow, diffusion of heat and steady sta...
