2011/11/9
In this paper, motivated by the idea from Courtois and Denuit et al.(2006), we derive extremal distribution for the discrete 5-convex stochastic ordering. As applications,We improve lower and upper bo...

Abstract: We develop an algorithm for computing the closure of a given nilpotent $G_0$-orbit in $\g_1$, where $\g_1$ and $G_0$ are coming from a $\Z$ or a $\Z/m\Z$-grading $\g= \bigoplus \g_i$ of a si...
Counterexamples to Ferromagnetic Ordering of Energy Levels

2011/8/26
Abstract: The Heisenberg ferromagnet has symmetry group ${\rm SU}(2)$. The property known as ferromagnetic ordering of energy levels (FOEL) states that the minimum energy eigenvalue among eigenvectors...
Ordering of small particles in one-dimensional coherent structures by time-periodic flows
time-periodic flows small particles Ordering one-dimensional coherent structures

2011/7/7
Small particles transported by a fluid medium do not necessarily have to follow the flow. We show that for a wide class of time-periodic incompressible flows inertial particles have a tendency to spon...

Supply chain model for the retailer's ordering policy under two levels of delay payments in fuzzy environment
Fuzzy numbers Function Principle
font style='font-size:12px;'>
2010/9/21
In this paper we discuss the retailer’s ordering policy under two levels of delay payments by considering the selling price per item to be higher than the purchasing cost per item. The demand and sell...
Retailer's pricing and ordering strategy for Weibull distribution deterioration under trade credit in declining market
Finance Weibull deterioration trade credit
font style='font-size:12px;'>
2010/9/21
In this research article, an ordering and pricing policy is formulated for a retailer when the supplier offers a delay in payments to settle the accounts against the retailer’s due. The problem is to ...
Ordering subsets of (partially) ordered sets: Representation theorems
partial orders ordering subsets of a poset
font style='font-size:12px;'>
2010/9/20
In many practical situations, we have a (partially) ordered set V of different values. For example, we may have the set of all possible values of temperature, or the set of all possible degrees of con...
