Our analysis provides necessary and sufficient conditions for allocation of the roots in the complex open left half-plane what guarantees asymptotic stability of the differential-difference equation. The conditions are expressed explicitly in terms of complex coefficients of the characteristic exponential polynomial, what makes them easy to use in applications. We show examples including those for retarded PDEs in an abstract formulation.}, type={Article}, title={Conditions for asymptotic stability of first order scalar differential-difference equation with complex coefficients}, URL={http://www.czasopisma.pan.pl/Content/128389/PDF/art07_int.pdf}, doi={10.24425/acs.2023.146962}, keywords={first order differential-difference equation with complex coefficients, stability ofdifferential-difference equation, characteristic exponential polynomial of differential-differenceequation, retarded differential-difference equation (DDE)}, }
