## Abstract In this paper we prove subelliptic estimates for operators of the form ฮ__~x~ +__ ฮป^2^ (__x__)__S__ in โ__^N^__ = โ ร โ, where the operator __S__ is an elliptic integro โ differential operator in โ__^N^__ and ฮป is a nonnegative Lipschitz continuous function.
## A characterization of superposition operators with local properties By GOTTFRIED BRUCKNER of Berlin (Eingegengen am 2.10.1980) In [ 11 it was shown that if A is a nontrivial superposition operator from Lp into L, with the property on a fixed hall then a 5 p / q and on t,he whole space. also su
