The Weierstrass elliptic function is a fundamental object in the theory of elliptic functions, which are special functions that have a periodic nature in two directions. These functions are used extensively in various fields of mathematics, including complex analysis, algebraic geometry, and number theory.

 View more
For a period lattice Λ⊂C, the Weierstrass elliptic function is the normally convergent lattice sum
℘Λ​(z)=z21​+∑ω∈Λ∖{0}​((z−ω)21​−ω21​).
(1)
It is an even elliptic function with a double pole of principal part (z−ω)−2 and zero residue at every point ω of the period lattice.
