AbstractThe authors consider the impulsive differential equation with Monge-Ampère operator in the form of {((u′(t))n)′=λntn−1f(−u(t)),t∈(0,1),t≠tk,k=1,2,…,m,Δ(u′)n|t=tk=λIk(−u(tk)),k=1,2,…,m,u′(0)=0,u(1)=0,$$\textstyle\begin{cases} ( (u'(t) )^{n} )'=\lambda nt^{n-1}f (-u(t) ), \quad t\in(0,1), t\neq t_{k}, k=1, 2, \ldots, m, \\ \Delta (u' )^{n}|_{t=t_{k}}=\lambda I_{k} (-u(t_{k}) ), \quad k=1, 2, \ldots , m, \\ u'(0)=0, \quad\quad u(1)=0, \end{cases} $$ where λ is a nonnegative parameter and n≥1$n\geq1$. We show the existence, uniqueness, and continuity results. Our approach is largely based on the eigenvalue theory and the theory of α-concave operators. The nonexistence result of a nontrivial convex solution is also studied by taking advantage of the internal geometric properties related to the problem.
