Boundary-value problems for differential-difference equations with perturbations in shifts of arguments are considered. Necessary and sufficient conditions for the fulfillment of Gårding-type inequalities in algebraic form are obtained. Continuous dependence of solutions of these problems on shifts of arguments is examined.
Keywords: boundary-value problem, differential-difference equation, strong ellipticity, Gårding inequality.
