Given that the theory of Stieltjes differential equations covers the framework of impulsive problems with fixed-time impulses, in the present work we generalize this setting by allowing the occurrence of fixed-time impulses, as well as the occurrence of state-dependent impulses. Along with an existence result obtained under an overarching set of assumptions involving Stieltjes integrals, it is showed that a least and a greatest solution can be found. %L acta76529 %T Fixed-time and state-dependent time discontinuities in the theory of Stieltjes differential equations %A Satco Bianca %K DifferenciĂĄlegyenlet
