Title: The isoperimetric problem in the 2-dimensional Finsler space forms with k = 0. II,
Abstract: This paper is a continuation of the second author's previous work. We
investigate the isoperimetric problem in the 2-dimensional Finsler space form
$(F_B, B^2(1))$ with $k=0$ by using the Holmes-Thompson area and prove that the
circle centered the origin achieves the local maximum area of the isoperimetric
problem.
