This paper investigates the asymptotic behavior of solutions of an integral equation of the Allen-Cahn type as |x| approaches infinity, with certain conditions on uniform continuity and integrability. The study reveals the limits of the solutions under various scenarios.
In this paper, we study the asymptotic behavior of solutions of an integral equation of the Allen-Cahn type in R-n u(x)=(l) over right arrow +C*integral(Rn)u(y)(1-|u(y)|(2))|1-|u(y)|(2)|(p-2)/|x-y|(n-alpha)dy , when |x| -> infinity. Here u:R-n -> R-k is uniformly continuous, and k >= 1, n >= 2, alpha is an element of (0, n) and p-1>n/n-alpha. In addition, (l) over right arrow is an element of R-k C-* is a real constant. If 1-|u|(2)is an element of L-s(R-n) s is an element of [1, infinity), we know that |u| -> 1 when |x| -> infinity. Furthermore, we prove that if 1-|u|(2)is an element of L-s(R-n) s is an element of[1,n/alpha(p-1)) <(l)over right arrow> x| -> infinity, and hence (l) over right arrow|=1 1-|u|2 is an element of Ls(Rn) s is an element of[1,n alpha(p-2))
