Abstract: | This paper is composed of two parts. In the first part closedness and compactness results are given for a sequence of nonlinear elliptic operators of the form , with monotone-type assumptions on the Aα's. These results are then used in the second part to derive existence theorems for a quasi-variational inequality related to some questions from nonlinear heat flow. This quasi-variational inequality involves a second-order operator as above and an implicit obstacle of the Signorini type on the boundary. |
