A bound for the complexity of any algebraic criterion, giving necessary and sufficient conditions for the stability of digital recursive filters is proposed, in 1-D and 2-D cases. For this, we show that the set of the 1-D Schur polynomials with a degree not greater than n, in the (n+1)-dimensional space of the polynomial coefficients, is connex and its boundary is a hypedace which has an irreducible equation.
