On Multiwell Liouville Theorems in Higher Dimensions

چکیده
We consider certain subsets of the space of n × n matrices of the form K = ∪i=1SO(n)Ai, and we prove that for p > 1, q ≥ 1 and for connected Ω ′ ⊂⊂ Ω ⊂ IR, there exists positive constant a < 1 depending on n, p, q,Ω,Ω such that for ε = ‖dist(Du,K)‖ Lp(Ω) we have infR∈K ‖Du−R‖ p Lp(Ω′) ≤ Mε1/p provided u satisfies the inequality ‖D2u‖ Lq(Ω) ≤ aε1−q . Our main result holds whenever m = 2, and also for generic m ≤ n in every dimension n ≥ 3, as long as the wells SO(n)A1, . . . , SO(n)Am satisfy a certain connectivity condition. These conclusions are mostly known when n = 2, and they are new for n ≥ 3.

Counter-example for Liouville theorems for indefinite problems on half spaces
We show that nonlinear Liouville theorems does not hold in general for indefinite problems on half spaces. Thus, in order to use blow-up method to obtain a priori estimates of indefinite elliptic equations, one has to impose assumptions on the nodal set of nonlinearity. The counter example is constructed by shooting method in one-dimensional case and then extended to higher dimensions.
متن کاملLiouville-type theorems and decay estimates for solutions to higher order elliptic equations
Liouville-type theorems are powerful tools in partial differential equations. Boundedness assumption of solutions are often imposed in deriving such Liouville-type theorems. In this paper, we establish some Liouville-type theorems without the boundedness assumption of nonnegative solutions to certain classes of elliptic equations and systems. Using a rescaling technique and doubling lemma devel...
متن کاملLiouville theorems for stable Lane-Emden systems and biharmonic problems
We examine the elliptic system given by −∆u = v, −∆v = u, in R , (1) for 1 < p ≤ θ and the fourth order scalar equation ∆u = u, in R , (2) where 1 < θ. We prove various Liouville type theorems for positive stable solutions. For instance we show there are no positive stable solutions of (1) (resp. (2)) provided N ≤ 10 and 2 ≤ p ≤ θ (resp. N ≤ 10 and 1 < θ). Results for higher dimensions are also...
متن کاملSolving Inverse Sturm-Liouville Problems with Transmission Conditions on Two Disjoint Intervals
In the present paper, some spectral properties of boundary value problems of Sturm-Liouville type on two disjoint bounded intervals with transmission boundary conditions are investigated. Uniqueness theorems for the solution of the inverse problem are proved, then we study the reconstructing of the coefficients of the Sturm-Liouville problem by the spectrtal mappings method.
متن کاملOn inverse problem for singular Sturm-Liouville operator with discontinuity conditions
In this study, properties of spectral characteristic are investigated for singular Sturm-Liouville operators in the case where an eigen parameter not only appears in the differential equation but is also linearly contained in the jump conditions. Also Weyl function for considering operator has been defined and the theorems which related to uniqueness of solution of inverse proble...
