I: The elliptic case. %D 1988 %@ 0392-4033 %U https://hdl.handle.net/20.500.14352/57517 %X The authors study the behaviour of the solution of the Signorini problem at the boundary. 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. %~
