On the regularity of the solutions to the 3D Navier–Stokes equations: a remark on the role of the helicity
We show that if velocity and vorticity are orthogonal at each point (and they become
orthogonal fast enough) then solutions of the 3D Navier–Stokes equations are smooth. This …

Asymptotic expansions with exponential, power, and logarithmic functions for non-autonomous nonlinear differential equations
This paper develops further and systematically the asymptotic expansion theory that was
initiated by Foias and Saut in (Ann Inst H Poincaré Anal Non Linéaire, 4 (1): 1–47 1987). We …
