It's named after the French mathematician Pierre Penard, who was one of its main founders and later made significant contributions to the theory. The Penbard conjecture is a deep result in algebraic geometry that has remained unsolved for over 50 years. It states: Let P be a projective variety defined by an equation f(x_1, x_2,
