👉 The term "hemielliptic" refers to a mathematical concept in differential equations, specifically related to elliptical curves. An elliptic curve is a curve that has an equation of the form y^2 = x^3 + ax+b where a and b are constants. The term "hemielliptic" describes this type of curve as it involves two different types of points on the curve: the origin (the point (0, 0)) and one of the foci
