Quasielliptic Operators and Equations Not Solvable with Respect to the Higher Order Derivative

详细

We consider a class of quasielliptic operators in Rⁿ and establish the isomorphism property in special weighted Sobolev spaces. In more general weighted spaces, we obtain the unique solvability conditions for quasielliptic equations and prove estimates for solutions. Based on the obtained results, we study the solvability of the initial problem for equations that are not solvable with respect to the higher order derivative.
