Elementary Number Theory - Joshua

1.1 Definition The number d divides the number n if there is a k such that n = dk. (Alternate terms are: d is a divisor of n, or d is a factor of n, or n is a multiple of d.) This relationship between d and n is symbolized d | n. The symbol d - n means that d does not divide n. Note that the symbol d | n is different from the fraction symbol ...

Lecture 7 — Spectral methods 7.1 Linear algebra review

Lecture 7 — Spectral methods 7.1 Linear algebra review 7.1.1 Eigenvalues and eigenvectors Definition 1. A d ×d matrix M has eigenvalue λ if there is a d-dimensional vector u 6= 0 for which Mu = λu. This u is the eigenvector corresponding to λ. In other words, the linear transformation M maps vector u into the same direction. It is ...
