- \(\epsilon\) "Is an element of".
- \(\sim\) "Is equivalent to", see equivalence relations. Also "is row equivalent to" for matrices.
- \(\mathbb{R}\) The real numbers.
- \(I_{n}\) The \(n \times n\) identity matrix.
- \(P_{n}^{\mathbb{F}}\) The vector space of polynomials of degree at most \(n\) with coeficients in the field \(\mathbb{F}\).
- \(\mathbb{M}_{k}^{r}\) The vector space of \(r \times k\) matrices.
