Inequalities for convolution ratios under local approximation
Inequalities Convolution ratios Local limit theorems
2010/9/14
This paper studies preservation of the convolution property under locally approximating functions for sums of independent random variables. Upper and lower bounds for limits of convolution ratios are ...

In the last few years Turkey experienced a serious financial crisis.In the aftermath of this crisis, immediate economic effects of the crisis were felt almost in all areas of the business world, and s...
The distributions of sums, products and ratios of inverted bivariate beta distribution
Bivariate inverted beta distributions Sums Ratios Percentiles
2010/9/14
In this paper we derive the exact distributions of sums, products, and ratios of two random variables when they follow the bivariate inverted beta distribution. Forms of the probability density functi...
A Monotonicity Property of Ratios of Symmetric Homogeneous Means
Monotonicity Strong inequalities Extended mean values Gini's mean Seiffert's mean Relative metrics
2008/7/3
We study a certain monotonicity property of ratios of means, which we call a strong inequality. These strong inequalities were recently shown to be related to the so-called relative metric. We also us...
Multiscale Domain Decomposition Methods for Elliptic Problems with High Aspect Ratios
multiscale elliptic problems domain decomposition
2007/12/11
In this paper we study some nonoverlapping domain decomposition methods for solving a class of elliptic problems arising from composite materials and flows in porous media which contain many spatial s...
