We study the nonlinear Hodge systemdω=0 and δ(ρ(|ω|2)ω)=0 for an exterior form ω on a compact oriented Riemannian manifold M, where ρ(Q) is a given po We introduce some Hilbert complexes involving second-order tensors on flat compact manifolds with boundary that describe the kinematics and the kinetics of motion in nonlinear elasticity. We then use the general framework of Hilbert complexes to write Hodge-type and Helmholtz-type orthogonal decompositions for second-order tensors.

Nonlinear Hodge Theory on Manifolds with Boundary Article Full-text available Dec 1999 We investigate when the Chevalley-Eilenberg differential of a complex Lie algebroid on a manifold with boundary admits a Hodge decomposition. We introduce the concepts of Cauchy-Riemann structures, elliptic and non-elliptic boundary points and Levi-forms, which we use to define the notion of q-convexity. We show that the Chevalley-Eilenberg complex of an Duality methods are used to generate explicit solutions to nonlinear Hodge systems, demonstrate the well-posedness of boundary value problems, and reveal, via the Hodge–Bäcklund transformation, underlying symmetries among superficially different forms of the equations.

Harmonic maps are nonlinear analogues of harmonic functions or, if one considers their differentials, harmonic 1-forms. As such, one can expect analogues of Hodge theoretic results about harmonic 1-forms. Harmonic maps arise as critical points for the energy functional on maps between two Riemannian manifolds. If M, N are Riemannian manifolds and f : M –+ N is a 1.1 Introduction Weyl’s law is in its simplest version a statement on the asymptotic growth of the eigenvalues of the Laplacian on bounded domains with Dirichlet and Neumann boundary conditions. In the typical applications in physics one deals either with the Helmholtz wave equation describing the vibrations of a string, a membrane (drum), a mass of air in a concert

L Ωp,q. The Hodge decom-position tells us that this holds when we pass to cohomology as well, but only for a special class of complex manifolds (importantly, there are complex manifolds for which the decomposition does not hold, e.g. Hopf surfaces) The goal of the course is to give an introduction to the basic results in Hodge theory. The prerequisites are: familiarity with algebraic varieties and sheaf cohomology (no familiarity with scheme theory is required) and with smooth manifolds (the

This research investigates the relationship between simplicial ZΛcohomology and L 2 harmonic forms through the integration of differential forms over simplexes within a smooth triangulation of complete oriented Riemannian manifolds. By establishing conditions on the manifold, particularly those related to the injectivity radius and curvature tensor boundedness, a de Rham-Hodge In this paper, we establish some general Kastler–Kalau–Walze type theorems on any dimensional manifolds with boundary for twisted Dirac operators.

The Hodge theorem asserts the existence and uniqueness of a harmonic form in every cohomology class of a Riemannian manifold M. Nonlinear Hodge theory deals with the analogous problem for ρ -harmonic forms. In this work, we prove a nonlinear Hodge theorem by the heat flow method for a class of densities ρ with unrestricted polynomial p, q -growth (see Abstract In this paper, we establish some general Kastler-Kalau-Walze type theorems for any dimensional manifolds with boundary which generalize the results in [S.

Nonlinear Hodge Theory on Manifolds with Boundary Article Full-text available Dec 1999 The classical Hodge-de Rham theorem for Riemannian manifolds establishes an isomorphism between the de Rham cohomology groups and the groups of harmonic forms living on the manifold. This paper proves a nonlinear Hodge theorem modeled on a regular Neumann problem for the global prolongation of the gas dynamics equation (with infinite sonic speed) to a Riemannian manifold with boundary and with a finite set of

On a complex manifold, a Hermitian metric is a com-plex analogue of Riemannian metric. To be precise, a Hermitian metric h is a smoothly varying Hermitian inner product on each The paper [1] says very little about the boundary conditions (which for forms are far from obvious), but the boundary conditions are carefully studied in [1].

We develop a Fredholm Theory for the Hodge Laplacian in weighted spaces on ALG$^*$ manifolds in dimension four. We then give several applications of this theory. Abstract We study boundary-value problems with mixed boundary conditions in weakly Lipschitz domains of compact boundaryless Riemannian Lipschitz manifolds. These include the case of the Maxwell system, the Hodge-Dirac operator, and the Hodge-Laplacian. Our approach brings to bear tools from functional analysis, differential geometry, harmonic analysis, and topology. In this paper, we establish a Hodge-type decomposition for the LP space of differential forms on closed (i.e., compact, oriented, smooth) Riemannian manifolds. Critical to the proof of this result is establishing an LP estimate which contains, as a

We study symplectic Laplacians on compact symplectic manifolds with boundary. These Laplacians are associated with symplectic cohomologies of di erential forms and can be of fourth-order. We introduce several natural boundary conditions on di erential forms and use them to establish Hodge the-ory by proving various form decomposition and also isomorphisms

In this paper, we obtain two Lichnerowicz type formulas for the Dirac–Witten operators. And we give the proof of Kastler–Kalau–Walze type theorems for the Dirac–Witten operators on 4-dimensional and 6-dimensional compact manifolds with (resp. without) boundary.

Nonlinear Hodge Theory on Manifolds with Boundary Article Full-text available Dec 1999 One key for the understanding and creation of new types of PDEs for mappings of nite distortion lies in the constant development and re nement of the de Rham cohomol-ogy theory which includes nonlinear boundary value problems on manifolds. We dignify these equations by calling them the Hodge systems. The intent of this paper is first to provide a comprehensive and unifying development of Sobolev spaces of differential forms on Riemannian manifolds with boundary. Second, is the study of a particular class of nonlinsar, first order, elliptic PDEs called Hodge systems. The Hodge systems are far reaching extensions of the Cauchy-Riemann system and solutions are referred to as

These notes provide an exposition on obtaining the wellknown standard results of quasiregular maps on Riemannian manifolds, given the corresponding theory in the Euclidean setting. We recall several different approaches to first-order Sobolev spaces between Riemannian manifolds, and show that they result in equivalent definitions of quasiregular maps. We explain

It demonstrates that, unlike closed manifolds where harmonic forms must be both closed and co-closed, connected manifolds with non-empty boundaries can harbor harmonic forms that are exact yet not derived from harmonic (p-1)-forms.
