Equations with nonnegative characteristic form. I
Journal of Mathematical Sciences, 2009This is the second part (Chapters 3--6) of a two-part work which is aimed at presenting the foundations of the general theory of second order partial differential equations with nonnegative characteristic form. It is devoted to the anniversary of the famous Russian mathematician O. A. Oleinik and is based on a series of joint papers of O. A.

Characteristics Analysis of the Parabolized Stability Equations
Studies in Applied Mathematics, 1994Some mathematical details of the parabolized stability equations (PSE) [4] are investigated. In particular, the sources of (unwanted) ellipticity in these equations are identified and suggestions are made for their suppression. Both the compressible and incompressible equations in primitive‐variable formulation are discussed.
