Under certain conditions on k,fandh, using viscosity sub- and super solution method with the aid of comparison principle, we establish the existence of a unique positive viscosity solution. This work extends and complements the earlier works on semilinear and singular elliptic equations with sublinear nonlinearity.falsePositive solutions | Pucci’s operator | Singular and sublinear nonlinearity | Viscosity solutionsArticle166054541 August 20176148arJournal3
