A higher-order parabolic wave equation

The Journal of the Acoustical Society of America, 1987
A higher-order paraboliclike approximation to the wave equation is presented. An implicit finite-difference discretization of the equation is implemented and its stability is discussed. The accuracy of the treatment of wide-angle propagation is examined by comparing computed solutions with exact solutions.

HIGHER-ORDER QUASILINEAR PARABOLIC EQUATIONS WITH SINGULAR INITIAL DATA

Communications in Contemporary Mathematics, 2006
As a basic model, we study the 2mth-order quasilinear parabolic equation of diffusion-absorption type [Formula: see text] where Δm,pis the 2mth-order p-Laplacian [Formula: see text].We consider the Cauchy problem in RN× R+with arbitrary singular initial data u0≠ 0 such that u0(x) = 0 for any x ≠ 0.

On linear higher-order parabolic equations in Morrey spaces

Analysis and Applications, 2023
In this paper, linear higher-order parabolic equation is shown to define a semigroup in Morrey spaces. For higher-order diffusion equation, the associated semigroup is proved analytic and sharp semigroup estimates in Morrey scale are derived. The analysis also includes semigroups in Morrey scale related to solving linear higher-order fractional ...

Inequalities for Nonlocal Parabolic and Higher Order Elliptic Equations

SIAM Review, 1967
Abstract : A general method is illustrated for obtaining L(2) bounds for nonlocal problems by using known bounds for corresponding strictly differential problems. The method is applied to obtain L(2) and pointwise bounds for perturbed second order parabolic and fourth order elliptic problems. (Author)
