ZarankiewiczDB,

an online database of Zarankiewicz numbers. home; recent; tables; submit; theorems & references

$\TeX$ commands are available via MathJax; for example, $\sum_{i = 1}^{\mu} a_i$ will be rendered as $\sum_{i = 1}^{\mu} a_i$, and

$$w(R'_1) > w(R_1) \implies A' <^{\mathrm{row}}_{w\mathrm{lex}} A$$

will be rendered as $$w(R'_1) > w(R_1) \implies A' <^{\mathrm{row}}_{w\mathrm{lex}} A$$ in display mode.

You can link to a matrix, bound or comment by its ID: for example, [[matrix:1]] will be rendered as Matrix 1, and [[comment:187|Example]] will be rendered as Example. To link to a Zarankiewicz number, e.g. [[number:chi(12,21)]] will be rendered as χ(12,21).

To cite a reference, write e.g. [[cite:Zar51]] for [Zar51] or [[cite:Rom75|p. 189]] for [Rom75, p. 189].
