Curve-straightening and the Palais-smale Condition
This paper considers the negative gradient trajectories associated with the modified total squared curvature functional ∫ k2 + ν ds. The focus is on the limiting behavior as ν tends to zero from the positive side. It is shown that when ν = 0 spaces of curves exist in which some trajectories converge and others diverge. In one instance the collection of critical points splits into two subsets. A...
متن کاملGlobal Inversion via the Palais-smale Condition
Fixing a complete Riemannian metric g on Rn, we show that a local diffeomorphism f : Rn → Rn is bijective if the height function f · v (standard inner product) satisfies the Palais-Smale condition relative to g for each for each nonzero v ∈ Rn. Our method substantially improves a global inverse function theorem of Hadamard. In the context of polynomial maps, we obtain new criteria for invertibi...
متن کاملGrand challenges: Grand opportunities
This document is intended to stimulate debate and discussion in preparation of the Escience Scoping Study Expert Seminar for archaeology and the historic environment. It is a tentative, partial and therefore controversial delineation of the challenges and opportunities which the E-science agenda presents archaeologists and the historic environment sector. It proposes areas of specific activity ...
متن کاملPalais-smale Approaches to Semilinear Elliptic Equations in Unbounded Domains
Let Ω be a domain in RN , N ≥ 1, and 2∗ = ∞ if N = 1, 2, 2∗ = 2N N−2 if N > 2, 2 < p < 2 ∗. Consider the semilinear elliptic problem −∆u+ u = |u|p−2u in Ω; u ∈ H 0 (Ω). Let H1 0 (Ω) be the Sobolev space in Ω. The existence, the nonexistence, and the multiplicity of positive solutions are affected by the geometry and the topology of the domain Ω. The existence, the nonexistence, and the multipli...
متن کاملPhysical Variational Principles Which Satisfy the Palais-smale Condition
1. Using variational techniques we have found conditions which insure the existence of trajectories to conservative dynamical systems which wind around singularities of the potential and are of the following four types: (la) periodic trajectories cutting arbitrary small neighborhoods of the singularities; (lb) periodic trajectories having arbitrary given period; (2a) trajectories joining two fi...
