In the present article we deal with the Dirichlet problem for a class of degenerate anisotropic elliptic
second-order equations with L^1-right-hand sides in a bounded domain of R^n (n >=2). This class is described by
the ...
We have established and investigated the sufficient conditions
of solvability of the Neumann problem for all classes of fourthorder
improperly elliptic equations in a unit disk K in the space C4(K)\
C3; (K).
