Abstract
We show that the tritronquée solution of the Painlevé equation that behaves algebraically for large with is analytic in a region containing the sector and the disk . This implies the Dubrovin conjecture, an important open problem in the theory of Painlevé transcendents. As a by-product, we obtain the value of the tritronquée and its derivative at zero, also important in applications, within less than rigorous error bounds.
