Abstract
We study a special discrete boundary value problem for a digital elliptic pseudo-differential operator in a discrete quadrant. Using a special periodic wave factorization for a symbol of the pseudo-differential operator we can construct a general solution of the pseudo-differential equation and then to choose appropriate boundary conditions for its unique solvability in corresponding Sobolev–Slobodetskii spaces. We also give a comparison between discrete and continuous solutions for boundary value problems under consideration.
