Where mathematics and astrophysics meet

Mathematicians Dmitry Khavinson and Genevra Neumann describe how their work on the Fundamental Theorem of Algebra led them to questions in astrophysics, specifically gravitational lensing. Their result resolves a conjecture of Sun Hong Rhie, establishing that the number of zeros of certain rational harmonic functions is 5n - 5.
