Higher order Cartan connections

Juraj Virsik (1996)

Archivum Mathematicum

A Cartan connection associated with a pair P ( M , G ' ) P ( M , G ) is defined in the usual manner except that only the injectivity of ω : T ( P ' ) T ( G ) e is required. For an r -th order connection associated with a bundle morphism Φ : P ' P the concept of Cartan order q r is defined, which for q = r = 1 , Φ : P ' P , and dim M = dim G / G ' coincides with the classical definition. Results are obtained concerning the Cartan order of r -th order connections that are the product of r first order (Cartan) connections.

Higher order jet involution

Miroslav Doupovec, Włodzimierz M. Mikulski (2007)

Czechoslovak Mathematical Journal

We introduce an exchange natural isomorphism between iterated higher order jet functors depending on a classical linear connection on the base manifold. As an application we study the prolongation of higher order connections to jet bundles.

Higher order linear connections from first order ones

Włodzimierz M. Mikulski (2007)

Archivum Mathematicum

We describe how find all f m -natural operators D transforming torsion free classical linear connections on m -manifolds M into r -th order linear connections D ( ) on M .

Higher order valued reduction theorems for classical connections

Josef Janyška (2005)

Open Mathematics

We generalize reduction theorems for classical connections to operators with values in k-th order natural bundles. Using the 2nd order valued reduction theorems we classify all (0,2)-tensor fields on the cotangent bundle of a manifold with a linear (non-symmetric) connection.

Higher symmetries of the Laplacian via quantization

Jean-Philippe Michel (2014)

Annales de l’institut Fourier

We develop a new approach, based on quantization methods, to study higher symmetries of invariant differential operators. We focus here on conformally invariant powers of the Laplacian over a conformally flat manifold and recover results of Eastwood, Leistner, Gover and Šilhan. In particular, conformally equivariant quantization establishes a correspondence between the algebra of Hamiltonian symmetries of the null geodesic flow and the algebra of higher symmetries of the conformal Laplacian.

Higher-order phase transitions with line-tension effect

Bernardo Galvão-Sousa (2011)

ESAIM: Control, Optimisation and Calculus of Variations

The behavior of energy minimizers at the boundary of the domain is of great importance in the Van de Waals-Cahn-Hilliard theory for fluid-fluid phase transitions, since it describes the effect of the container walls on the configuration of the liquid. This problem, also known as the liquid-drop problem, was studied by Modica in [Ann. Inst. Henri Poincaré, Anal. non linéaire 4 (1987) 487–512], and in a different form by Alberti et al. in [Arch. Rational Mech. Anal.u is a scalar density function and...

Hodge theory for twisted differentials

Daniele Angella, Hisashi Kasuya (2014)

Complex Manifolds

We study cohomologies and Hodge theory for complex manifolds with twisted differentials. In particular, we get another cohomological obstruction for manifolds in class C of Fujiki. We give a Hodgetheoretical proof of the characterization of solvmanifolds in class C of Fujiki, first stated by D. Arapura.
