), also called pe, is used for the Weierstrass's elliptic function
. It is occasionally used for the power set, although for that purpose a cursive capital, rather than lower-case, p is more widespread. It is named after the German mathematician Karl Weierstrass

Mathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...
