In particular a necessary and quasi-sufficient condition for the existence of a nonempty coincidence set and some estimates on the location of the coincidence set are proved.journal articlehttp://umi.dm.unibo.it/metadata only access517.956.2Signorini problemnonlinear boundary conditionformation and the location of the coincidence setboundary behaviourEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
