Fourth-Order Tensors

2009
Fourth-order tensors play an important role in continuum mechanics where they appear as elasticity and compliance tensors. In this section we define fourth-order tensors and learn some basic operations with them. To this end, we consider a set \(\mathcal{L}{\text{ in}}^{n}\) of all linear mappings of one second-order tensor into another one within ...

Fourth-order analogies to the Painlevé equations

Journal of Physics A: Mathematical and General, 2002
Summary: Using the compatibility condition for the Painlevé equations, several new fourth-order ordinary differential equations (ODEs) that are analogies of the Painlevé equations are found. Isomonodromic linear problems for these equations are given. Special solutions of the fourth-order ODEs obtained are discussed.

Fourth-order spectra of mixture processes

International Conference on Acoustics, Speech, and Signal Processing, 2003
The hypothesis for non-Gaussian processes higher-order spectra contain information that usually is not contained in second-order spectra is proved for a special case of the trispectrum using mixture processes. Specifically, the fourth-order cumulant spectrum is shown to differentiate between a Gaussian process and a non-Gaussian mixture process ...

Virtual control for fourth-order problems and for heterogeneous fourth-order second-order coupling

2003
We consider both approximation of fourth-order problems derived, e.g., the Kirchoff plate model, and heterogeneous coupling between a fourth-order problem and a reduced second-order problem, describing a plate-membrane model. The multidomain virtual control approach is used. This paper is devoted to the analysis and construction of the cost function al

Spectra of fourth-order quasilinear problems

Mathematics and Computers in Simulation, 2007
Some properties of the eigenvalues of the fourth-order quasilinear system \[ (| u''(t)| ^{p-2} u''(t))''=\lambda | u(t)| ^{p-2} u(t),\qquad t\in[0,1], \] subject to Dirichlet, Navier and Neumann boundary conditions are recalled. Furthermore, an algorithm developed by the author in earlier works to compute these eigenvalues efficiently is recalled and ...
