In particular, we find the Zeldovich Barenblatt type solution to the cross diffusive system. The asymptotic behavior of self-similar solutions are analyzed for both the slow and fast diffusive regimes. It is shown that coefficients of the main term of the asymptotic of solution satisfy some system of nonlinear algebraic equations.</p></abstract><kwd-group xml:lang="en"><kwd>cross-diffusive system</kwd><kwd>non-divergence form</kwd><kwd>finite speed</kwd><kwd>perturbation</kwd><kwd>global solutions</kwd><kwd>asymptotic behavior</kwd><kwd>numerical analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Samarskii A.A., Galaktionov V.A., Kurdyumov S.P., Mikhailov A.P.
