Stability of scalar difference equations with one delay is investigated. Restrictions are layed consequently on coefficients and delays of the linear nonautonomous equation of general form. First we consider the equation with arbitrary coefficients and delays, then the equation with limited delays, the one with constant coefficients, and, at last, the autonomous equation. It is demonstrated how the region of stability is expanded.
Keywords: difference equations, equations with delay.
