Abstract
In this paper, we deal with fractional [Formula: see text]-Laplace Kirchhoff equations with exponential growth of the form [Formula: see text] where [Formula: see text] is a positive parameter, [Formula: see text], [Formula: see text] and [Formula: see text]. Under some appropriate conditions for the nonlinear function [Formula: see text] and potential function [Formula: see text], and with the help of penalization method and Lyusternik–Schnirelmann theory, we establish the existence, multiplicity and concentration of solutions. To some extent, we fill in the gaps in [W. Chen and H. Pan, Multiplicity and concentration of solutions for a fractional [Formula: see text]-Kirchhoff type equation, Discrete Contin. Dyn.
