In this work we propose a Filippov-type lemma for the differential inclusion () ∈ (, ()), (0) = 0 , (0.1) where ∶ [0, ] × ℝ ⇝ ℝ is a given multifunction and is a finite Borel signed measure on [0, ] (possibly atomic). By a solution of (0.1) we mean a function ∶ [0, ] ⟶ ℝ such that (0) = 0 and () = 0 + ∫ () () () f or > 0, where (⋅) is a-integrable function such that () ∈ (, ()) for-almost every ∈ [0, ] and () stands for either (0, ] for each ∈ or [0,). Such setting leads to at least two nonequivalent notions of a solution to (0.1) and therefore we formulate two different Filippov-type inequalities (Theorems 2.1 and 2.2). These two concepts coincide in case of the Lebesgue measure. The purpose of our considerations is to cover a class of impulsive control systems, a class of stochastic systems and differential systems on time scales.
