On the asymptotic growth of positive solutions to a nonlocal elliptic blow-up system involving strong competition

Abstract: Abstract. For a competition-diffusion system involving the fractional Laplacian of the formwhith s ∈ (0, 1), we prove that the maximal asymptotic growth rate for its entire solutions is 2s. Moreover, since we are able to construct symmetric solutions to the problem, when N = 2 with prescribed growth arbitrarily close to the critical one, we can conclude that the asymptotic bound found is optimal. Finally, we prove existence of genuinely higher dimensional solutions, when N ≥ 3. Such problems arise, for example… Show more

“…For the case of standard diffusion, both the asymptotic analysis and the properties of the segregated limiting profiles are fairly well understood, we refer to [13,15,16,24,28] and references therein. Instead, when the diffusion is nonlocal and modeled by the fractional Laplacian, the only known results are contained in [29,30,31,32]. As shown in [29,30], estimates in Hölder spaces can be obtained by the use of fractional versions of the Alt-Caffarelli-Friedman (ACF) and Almgren monotonicity formulae.…”

“…It is easy to see, by a Schwarz symmetrization argument, that ν ACF s is achieved by a pair of complementary spherical caps (ω θ , ω π−θ ) ∈ P 2 with aperture 2θ and θ ∈ (0, π) (for a detailed proof of this kind of symmetrization we refer to [31]), that is:…”
