Hardy-type inequality with double singular kernels
A Hardy-type inequality with singular kernels at zero and on the boundary ∂Ω is proved. Sharpness of the inequality is obtained for Ω= B 1(0).
Time–Harmonic Behaviour of a Cracked Piezoelectric Solid by BIEM
ACM Computing Classification System (1998): J.2, G.1.9 Time–harmonic behaviour of a cracked piezoelectric finite solid is studied by nonhypersingular traction Boundary Integral Equation Method (BIEM). A numerical solution for Crack Opening Displacement (COD) and Stress Intensity Factor (SIF) is obtained by using Mathematica. Several examples are presented to demonstrate the dependence of the solution on the crack position. The authors acknowledge the support of the Bulgarian...
The Asymptotic Behaviour of the First Eigenvalue of Linear Second-Order Elliptic Equations in Divergente Form
2000 Mathematics Subject Classification: 35J70, 35P15. The asymptotic of the first eigenvalue for linear second order elliptic equations in divergence form with large drift is studied. A necessary and a sufficient condition for the maximum possible rate of the first eigenvalue is proved.
Hardy-Type Inequalities with Weights
[Fabricant Alexander; Фабрикант Александър]; [Kutev Nikolai; Кутев Николай]; [Rangelov Tsviatko; Рангелов Цвятко] Hardy-type inequality with weights is derived in abstract form. Particular cases are presented to demonstrate the applicability of the method and to show generalizations of existing results. Sharpness of inequalities is proved and the results are illustrated with several examples. 2010 Mathematics Subject Classification: 26D10.
