Failure of analytic hypoellipticity in a class of PDOs

O Costin, R D Costin

For the hypoelliptic differential operators $P = \partial_{x}^{2} + (x^{k} \partial_{y} - x^{l} \partial_{t})^{2}$ introduced by T. Hoshiro, generalizing a class of M. Christ, in the cases of $k$ …

Existence and uniqueness for a class of nonlinear higher-order partial differential equations in the complex plane

O Costin, S Tanveer

We prove existence and uniqueness results for nonlinear third order partial differential equations of the form $f_{t} - f_{y y y} = j = 0 \sum 3 b_{j} (y, t; f) f^{(j)} + r (y, t)$ w…

Asymptotic properties of a family of solutions of the Painleve equation PVI

O Costin, R D Costin

In this paper we study the asymptotic behavior for large argument of a family of solutions of the Painlevé equation P$_{\rm VI} arising in the context of Random Matrix Theory [1].…
