Bow curve

Bow curve

A bow curve is a quartic plane curve with the equation::x^4=x^2y-y^3. ,

The bow curve has a single triple point at x=0, y=0, and consequently is a rational curve, with genus zero. Expanding around zero, the three branches have series y_1 = x^2+x^4+3x^6+12x^8+55x^{10} cdotsy_2 = x - frac{1}{2}x^2 + frac{3}{8}x^3 - frac{1}{2}x^4 + cdotsy_3 = x - frac{1}{2}x^2 - frac{3}{8}x^3 - frac{1}{2}x^4 - ldots.

The nature of any singularity of a plane algebraic curve is defined by its link; the link for the singularity, an ordinary triple point, of the bow curve is illustrated below.
