The conifold point

Résumé :
A Laurent polynomial with positive coefficients has a distinguished non-degenerate critical point, namely the unique critical point with real positive coordinates. As a consequence, the quantum cohomology algebra of a toric Fano manifold contains a field as a direct summand. Also it gives a good evidence that the same holds for any Fano manifold. I'll discuss this story and its relation to mirror symmetry.
