ELLIPTIC FUNCTIONAL DIFFERENTIAL EQUATIONS WITH CONTRACTIONS AND EXTENSIONS OF INDEPENDENT VARIABLES OF THE UNKNOWN FUNCTION

摘要

This work is devoted to even-order partial differential equations containing contractions and extensions of independent variables in high-order terms. For such equations, we mainly study boundary-value problems in bounded domains of the space R~n. The only exception is Chap. 4, where the equation is considered in R~n.
