“…)-Kirchhoff type have been intensively studied in the recent years, because of their numerous and relevant applications in many fields of mathematics, for example, electrorheological fluids (see [2]), elastic mechanics ( [1]), image restoration ( [7]). For this type of operator combined with a system of Kirchhoff functions we recall [1,5,11]. Inspired by the above articles, we aim in this paper to prove, under minoration conditions on A i=1,2 and periodic conditions on F , the existence of solutions for the system (1) by applying variational method and Ekeland's principle.…”
