Vladimir Andreevich Mikhailets, Aleksandr Murach · Bulletin of the Polish Academy of Sciences Mathematics · 2008
We study a system of pseudodifferential equations which is elliptic in the Petrovskii sense on a closed smooth manifold. We prove that the operator generated by the system is a Fredholm operator in a refined two-sided scale of Hilbert function spaces. Ele
