EXISTENCE RESULTS FOR NONSMOOTHSECOND-ORDER DIFFERENTIAL INCLUSIONS,CONVERGENCE RESULT FOR A NUMERICALSCHEME AND APPLICATION TO THE MODELINGOF INELASTIC COLLISIONS

摘要

We are interested in the existence results for second-order differential inclusions, involv-ing finite number of unilateral constraints in an abstract framework. These constraints are described by a set-valued operator, more precisely a proximal normal cone to a time-dependent set. In order to prove these existence results, we study an extension of the numerical scheme introduced in 10 and prove a convergence result for this scheme.
