Degrees $d \geqslant \big( \sqrt{n}\, \log\, n\big)^n$ and $d \geqslant \big( n\, \log\, n\big)^n$ in the Conjectures of Green-Griffiths and of Kobayashi
Once first answers in any dimension to the Green-Griffiths and Kobayashi conjectures for generic algebraic hypersurfaces $\mathbb{X}^{n-1} \subset \mathbb{P}^n(\mathbb{C})$ have been reached, the principal goal is to decrease (to improve) the degree bounds, knowing that the `celestial' horizon lies near $d \geqslant 2n$. For Green-Griffiths algebraic degeneracy of entire holomorphic curves, we obtain: \[ d \,\geqslant\, \big(\sqrt{n}\,{\sf log}\,n\big)^n, \] and for Kobayashi-hyperbolicity (constancy of entire curves), we obtain: \[ d \,\geqslant\, \big(n\,{\sf log}\,n\big)^n. \] The latter improves $d \geqslant n^{2n}$ obtained by Merker in arxiv.org/1807/11309/. Admitting a certain technical conjecture $I_0 \geqslant \widetilde{I}_0$, the method employed (Diverio-Merker-Rousseau, Bérczi, Darondeau) conducts to constant power $n$, namely to: \[ d\ ,\geqslant\, 2^{5n} \qquad \text{and, respectively, to:} \qquad d \,\geqslant\, 4^{5n}. \] In Spring 2019, a forthcoming prepublication based on intensive computer explorations will present several subconjectures supporting the belief that $I_0 \geqslant \widetilde{I}_0$, a conjecture which will be established up to dimension $n = 50$.
