چکیده

A b stra c t. Here for a smooth bounded Euclidean domain-and a smooth Riemannian manifold N , we show that almost every smooth map ' : @-! N serves as boundary data for at most one energy minimizing map u :-! N [Theorem 5. 2]. We also obtain some uniform boundary regularity estimates for energy minimizers [Theorem 2. 1 ], which n ot only are important to our proof, but also imply some other properties of energy minimizers [Corollaries 2. 6{2.9] .

Uniqueness of Energy Minimizing Maps for Almost All Smooth Boundary Data

Here for a smooth bounded Euclidean domain Ω and a smooth Riemannian manifold N , we show that almost every smooth map φ : ∂Ω→ N serves as boundary data for at most one energy minimizing map u : Ω→ N [Theorem 5.2]. We also obtain some uniform boundary regularity estimates for energy minimizers [Theorem 2.1], which not only are important to our proof, but also imply some other properties of ener...

Harmonic Maps with Fixed Singular Sets

§ 0. Introduction Here, for a smooth domain Ω in R and a compact smooth Riemannian manifold N we study a space H consisting of all harmonic maps u : Ω → N that have a singular set being a fixed compact subset Z of Ω having finite m− 3 dimensional Minkowski content. This holds if, for example, Z is m− 3 rectifiable [F, 3.2.14]. We define a suitable topology on H using Hölder norms on derivatives...

Boundary Regularity and the Dirichlet Problem for Harmonic Maps

In a previous paper [10] we developed an interior regularity theory for energy minimizing harmonic maps into Riemannian manifolds. In the first two sections of this paper we prove boundary regularity for energy minimizing maps with prescribed Dirichlet boundary condition. We show that such maps are regular in a full neighborhood of the boundary, assuming appropriate regularity on the manifolds,...

A Theoretical and Experimental Study of Failure Maps of Sandwich Beams with Composite Skins and Honeycomb Core

Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...

Initial data for fluid bodies in general relativity

We show that there exist asymptotically flat almost-smooth initial data for Einstein-perfect fluid’s equation that represent an isolated liquid-type body. By liquid-type body we mean that the fluid energy density has compact support and takes a strictly positive constant value at its boundary. By almost-smooth we mean that all initial data fields are smooth everywhere on the initial hypersurfac...
