SOLVABILITY CONDITIONS FOR SOME DIFFERENCE OPERATORS N C APREUTESEI AND V A VOLPERT Received 24 docx

... the normally solvable operators with finite-dimensional kernels. Since at +∞ and −∞ the operators L + and L − coincide, we finally reduce L to an operator with constant coefficients. According to ... operators and associated polyno- mials are introduced. Under some speci c conditions on the polynomials, the operator is Fredholm and has the zero index. Solvability conditions...
