Theorems

The conformal mapping from the triangle to the half plane

The conformal map from the triangle in the z-plane with coordinates {0,0}, {1,0}, {1/2, ((Sqrt[3])/2)} to the upper half w-plane is given by w(z)==(1/2)+(27/(2 ((Β((1/3),(1/3)))^3))) ℘'(z-(e^((π i)/3));0,-(1/729) ((Β((1/3),(1/3)))^6)).

The (P^2)-equation

The (P^2) -equation can be cast in the form (((∂^2)z(τ))/(∂(τ^2)))==-(1/(8(π^2)))℘'(z(τ);{1,τ}).
