摘要

We prove the existence of solutions for a perturbed differential inclusion governed by a sweeping process with state dependent convex moving set \(\begin{aligned}\left\{ \begin{array}{l} -u'_g(t)\in N_{C(t,u(t))}(u(t))+F(t,u(t)),\; \mu _g-a.e. \; t\in (0,T]\\ u(0)=u_0\in C(0,u_0). \end{array} \right. \end{aligned}\) - u g ( t ) N C ( t , u ( t ) ) ( u ( t ) ) + F ( t , u ( t ) ) , μ g - a . e . t ( 0 , T ] u ( 0 ) = u 0 C ( 0 , u 0 ) . The novelty brought by our study is the involvement of the Stieltjes derivative \(u'_g\) u g with respect to a right-continuous nondecreasing function \(g:[0,T]\rightarrow {\mathbb {R}}\) g : [ 0 , T ] R , thus establishing a very wide framework containing ODEs, impulsive differential problems, dynamic inclusions on time scales or generalized differential problems. Here \(\mu _g\) μ g is the Stieltjes measure associated to g and \(N_{C(t,u(t))}(u(t))\) N C ( t , u ( t ) ) ( u ( t ) ) denotes the normal cone of C(tu(t)) at the point u(t).
