Lower bounds for volumes of nodal sets: an improvement of a result of Sogge-Zelditch
Lower bounds volumes of nodal sets Sogge-Zelditch
2011/8/22
Abstract: We use the Dong-Sogge-Zelditch formula to obtain a lower bound for the volume of the nodal sets of eigenfunctions. Our result improves the recent results of Sogge-Zelditch and in dimensions ...
Improvement of the Han-Kobayashi Rate Region for General Interference Channel-v2
Interference channel Input correlation Binning scheme
2011/2/28
Allowing the input auxiliary random variables to be correlated and using the binning scheme, the Han-Kobayashi (HK) rate region for general interference channel is partially improved. The obtained par...
An improvement upon unmixed decomposition of an algebraic variety
unmixed decomposition weakly non-degenerate conditions
2011/1/18
Decomposing an algebraic variety into irreducible or equidimensional components is a fundamental task in classical algebraic geometry and has various applications in modern geometry engineering. Sever...
A selective and gradual method for efficiency improvement of DEA models
Data Envelopment Analysis Efficiency Improvement algorithm
2010/9/10
Basic-DEA models have ability to calculate performance targets for inefficient DMUs which are used for efficiency improvement approaches. Unfortunately, these improvement approaches aren't selective a...
On improvement of uniform convergence of Lagrange interpolation polynomials
Lagrange interpolation polynomial uniform convergence
2010/9/14
Due to the Lagrange interpolation polynomials do not converge uniformly to arbitrary continuous functions, in this paper, a new interpolation polynomial is constructed by using the weighted average me...
The Grüss inequality is improved by adding a positive component to the left hand side.
Hilbert-Pachpatte Type Integral Inequalities and their Improvement
Hilbert's inequality Hilbert-Pachpatte type inequality Hö lder's inequality Jensen inequality
2008/7/1
In this paper, we obtain an extension of multivariable integral inequality of Hilbert-Pachpatte type. By specializing the upper estimate functions in the hypothesis and the parameters, we obtain many ...
Improvement of an Ostrowski Type Inequality for Monotonic Mappings and its Application for Some Special Means
Ostrowski's inequality Trapezoid inequality Special means
2008/7/1
We first improve two Ostrowski type inequalities for monotonic functions, then provide its application for special means.
Improvement of the Non-uniform Version of Berry-Esseen Inequality Via Paditz-Siganov Theorems
Berry-Esseen inequality Paditz-Siganov theorems central limit theorem uniform and non-uniform bounds
2008/7/1
Abstract: We improve the constant in a non-uniform bound of the Berry-Esseen inequality without assuming the existence of the absolute third moment by using the method obtained from the ...
