  • Schur's recursive triangulation procedure Given a linear endomorphism f on a non-trivial finite-dimensional vector space E over an algebraically closed field 𝕜, one can always pick an eigenvalue μ of f whose corresponding eigenspace V is non-trivial. Given that E is also an inner product space, let bV and bW be othonormal bases for V and Vᗮ respectively. Then, the collection of vectors in bV and bW forms an othornomal basis bE for E, as the direct sum of V and Vᗮ is an internal decomposition of E. The matrix representation of f with respect to bE satisfies $$ \sideset{\mathrm{bE}}{\mathrm{bE}}{[f]} = \begin{bmatrix}

  • Model The author accompanies the symbolic discussions of the topic with vivid simulations depicting the physical effects of interest. The simulations all concern a system of $8$ electrons in which only their spins are taken into account, and the simulations are performed according to the scheme below. I precede the illustration of the scheme with the rationale for adopting such a setting. Rationale An electron only concerned of its spin is a two-level system which is the simplest to describe. A composite system of $8$ such two-level subsystems has $2^8 = 256$ eigenstates which serves narrative purposes well while keeping computations manageable. Though any composite system of two-level subsystems would suffice, the author favors a system of electrons for concreteness. Scheme

  • $$ \sum_{n=m}^\infty \frac{C}{n^{1+\epsilon}} \leq \int_{m-1}^\infty \frac{C}{x^{1+\epsilon}} \operatorname{d}! = \left[-\frac{C}{\epsilon x^\epsilon}\right]_{m-1}^\infty = \frac{C}{\epsilon (m-1)^\epsilon} - 0 < \infty $$ If $\lvert a_n \rvert$ is absolutely convergent, $\sum_{n=m}^\infty \frac{1}{n}$ is convergent by comparison, but this is contradicts with the fact that $\sum_{n=m}^\infty \frac{1}{n}$ is divergent.
