Abstract: We study the dynamics of domain walls in the Einstein-Born--Infeld-dilaton theory. A dilaton is nontrivially coupled with the Born-Infeld electromagnetic field. We find three different types of solutions consistent with the dynamic domain walls. For every case, the solutions have singularity. Furthermore, in these backgrounds, we study the dynamics of domain walls. We qualitatively plot various forms of the bulk metrics and the potential encountered by the domain walls. In many cases, depending upon the value of the parameters, the domain walls show a bouncing universe and also undergo an inflationary phase followed by a standard decelerated expansion.
