A Liouville comparison principle for solutions of semilinear elliptic second-order partial differential inequalities

Vasilii V. Kurta

We consider semilinear elliptic second-order partial differential inequalities of the form Lu +|u|q-1u < and = Lv +|v|q-1v (*) in the whole space Rn, where n > and = 2, q > 0 and L…
