I recently encountered a symbol $\wp$, and its meaning confuses me. For example, while $\forall$, $\angle$ have a definite meaning in mathematics, so what does the symbol $\wp$ mean?

  • One systematic way to lookup meanings is to lookup the csname in unimath-symbols.pdf and search for the corresponding unicode codepoint.

This is the Weierstrass's elliptic function.

According to wikipedia, "this symbol was used already at least in 1890. The first edition of A Course of Modern Analysis by E. T. Whittaker in 1902 also used it."
