The following list is an excerpt from an initialization file of MathJax and is to be understand, e.g. the first line, as: Use

\C

for $\C$.

            C: '\\mathbb{C}',        /* the complex numbers */
N: '\\mathbb{N}',        /* the natural numbers */
Q: '\\mathbb{Q}',        /* the rational numbers */
R: '\\mathbb{R}',        /* the real numbers */
Z: '\\mathbb{Z}',        /* the integer numbers */
ph: '\\varphi',
eps: '\\varepsilon',
th: '\\vartheta',

/* some extre macros for ease of use; these are non-standard! */
F: '\\mathbb{F}',        /* a finite field */
HH: '\\mathcal{H}',      /* a Hilbert space */
bszero: '\\boldsymbol{0}', /* vector of zeros */
