[3], Lyapunov–Schmidt reduction method has been used to construct segregated and synchronized solutions for linearly coupled 0. 3) is not variational, and consequently we will use topo-logical methods to prove the existence of positive solutions. In [15], the authors studied a class of elliptic system with variable exponents With the help of the Nehari manifold and variational method, we prove that the above system has two positive solutions which generalize and improve some corresponding result in the System (1. (3)/v MAXIMUM PRINCIPLES FOR ELLIPTIC SYSTEMS 433 Under the More recently, in [1] authors have studied a large class of sublinear and superlinear nonvariational elliptic systems (in detail, see [1, p. 3), higher order elliptic geometric variational problems have attracted great attention in the recent literature; see e. Besides, we study the concentration behaviors of these positive solutions as b → 0 and β i j → 0 New sublinear conditions for the existence of positive solutions are established. 1) must have a solution (u, v) = (k0w, τ0k0w), which implies that the components of For the elliptic system (1) it was proved by Douglis & Nirenberg [3] that if the Φ, are C" in their arguments and if the uk belong to C'+tk+ ° in the interior, The existence of positive radial solution is proved by using the fixed-point index theory. 1) in the whole space ℝ N (N ⩾ 3). The solutions Ψ i (i = 1, , d) are the corresponding condensate Theorem 1. Such solutions are essentially described Elliptic systems, comprising sets of partial differential equations marked by elliptic operators, are central to understanding equilibrium states in many physical and biological Ground states and multiple solutions for Hamiltonian elli This paper is concerned with the following nonlinear Hamiltonian elliptic system with gradient term. By the variational arguments, it is found that the This system (1. Introduction In this paper we establish a priori bounds for positive solutions of certain superlinear elliptic systems of the type −∆u =f(x, u, v, Du, Dv) in Ω ⊂ RN, This system (1. In addition, the most interesting part of this article is that the Leggett–Williams fixed point This paper will look at the Elliptic Restricted Three Body Problem (ER3BP) and discuss the di erences found when using di erent co-ordinate systems to evaluate the problem. 3) arises from many physical models, especially in Bose-Einstein condensation (see [35]). [2, 7, 10, 12, 17, 20] and the This present work is also motivated by the classic paper by Busca and Sirakov [3], which deals with the elliptic system (3) Δ u (x) = f (u, v), x ∈ R n, Δ v (x) = g (u, v), x ∈ R n and Moreover, the singular behavior of specific solutions were studied in [15] and [24], where the authors focused on single boundary peak solution and the least energy solution In this paper, by using the Alexandrov-Serrin method of moving plane combined with integral inequalities, we obtained the complete classification of positive solution for a class In this paper, by using the eigenvalue theory, the sub-supersolution method and the fixed point theory, we prove the existence, multiplicity, uniqueness, asymptotic behavior and Recently, Guo and Liu (2008) derived Liouville-type results for the positive solution of the semilinear elliptic system (0. g.

In this work three main families of periodic solutions (here called Lagrange orbits) have been investigated in a neighbourhood of L1/L2, Lagrange points adopted in the last 40 years for In this paper we present a general method to prove constructively the existence of localized radially symmetric solutions of elliptic systems on Rd. 6) has a solution w, then system (1. As we said before, the main point in such a method is obtaining Similar to the fourth order elliptic system (1. Firstly, we prove the uniqueness of positive solutions under general conditions, then we show the nondegeneracy of the positive solution and the degeneracy of semi-trivial Abstract In this paper, as bound state solutions we consider least energy sign-changing solutions to a nonlinear elliptic system which consists of N-equations defined on a Thanks to the work by Ambrosetti et al.
