Research

A paper resolves the Nirenberg-Treves conjecture: that condition ($\Psi$) is sufficient for local solvability for operators of principal type (Ann. of Math. 163 (2006), no. 2, 405-444).

Joint paper with Johannes Sjöstrand and Maciej Zworski about the pseudo-spectra of semi-classical operators (Comm. Pure Appl. Math. 57 (2004), no. 3, 384-415).

A preprint that studies pseudospectrum for systems of semiclassical operators, generalizing our CPAM paper (corrected version December 1, 2008). Accepted for publication in Analysis & PDE.

Another preprint that generalizes the Nirenberg-Treves conjecture to quadratic systems of principal type having constant characteristics.

Latest preprint that proves solvability and subellipticity results of quasi-symmetrizable systems.
