摘要
In the paper, we intend to analyze the existence of entire subsolutions to the p -k-Hessian equation1 Sk (& lambda;((Di(|Du|p-2Dju)) + & alpha;|Du|& beta;(p-1)I)) = f(u), x & ISIN; Rn, k where ,3 = 0 or 1, p & GE; 2 and & alpha; & GE; 0 is a constant. The necessary and sufficient conditions on f for the existence of entire subsolutions are established. Since ,3 = 0 or 1 and & alpha; & GE; 0 not & alpha; & EQUIV; 0, it is very difficult to judge the sign of second order derivative. We will overcome the difficulty by introducing a new technique.& COPY; 2023 Elsevier Ltd. All rights reserved.
