We generalize our results of [AP2] and [AP3] to the case of maximal dissipative operators. We obtain sharp conditions on a function analytic in the upper half-plane to be operator Lipschitz.
Ideal games, Ramsey sets and the Frechet-Urysohn property
Semiselective coideal Ramsey theory Frechet-Urysohn property
2010/12/8
It is shown that Matet’s characterization ([8]) of H-Ramseyness relative to a selec-tive coideal H, in terms of games of Kastanas ([5]), still holds if we consider semiselec-tivity ([2]) instead of se...
Global existence for the generalized two-component Hunter-Saxton system
Generalized Hunter-Saxton system global existence blow-up scenario
2010/12/1
e study the global existence of solutions to a two-component generalized Hunter-Saxton system in the periodic setting. We first prove a persistence result of the solutions. Then for some particular ch...
We derive a mesoscopic description of the behavior of a simple financial market where the agents can create their own portfolio between two investment alternatives: a stock and a bond. The model is de...
Labeled Ballot Paths and the Springer Numbers
Springer number snake of type Bn labeled ballot path labeled Dyck path
2010/12/3
The Springer numbers are defined in connection with the irreducible root systems of type Bn, which also arise as the generalized Euler and class numbers introduced by Shanks. Combinatorial interpretat...
Optimal Dividend and reinsurance strategy of a Property Insurance Company under Catastrophe Risk
Optimal dividend and reinsurance strategy Optimal return function Catastrophe risk
2010/12/15
We consider an optimal control problem of a property insurance company with proportional reinsurance strategy. The insurance business brings in catastrophe risk, such as earthquake and
flood.
Quasiconvexity at the boundary and concentration effects generated by gradients
Bounded sequences of gradients concentrations oscillations quasiconvexity
2010/11/30
We characterize generalized Young measures, the so-called DiPerna-Majda measures which are gener-ated by sequences of gradients. In particular, we precisely describe these measures at the boundary of ...
应力-强度相关性干涉的静态和动态可靠度计算模型
应力-强度干涉模型 可靠度计算 相关性 Copula 函数
2010/8/26
为解决机械零件可靠度计算中的应力-强度相关性干涉问题,根据两者负相关结构,运用Copula 函数的相关性理论,建立了静态和动态应力-强度相关性干涉模型. 根据综合应力和综合强度各构建分量之间的正相关性,给出了确定其分布的算法和估计相关程度参数的方法. 分析了相关程度参数的变化对相关性模型中Copula函数的影响. 结果表明,机械零件的可靠度随相关程度参数动态连续变化,下界与应力-强度完全负相关对应...

Statistical measures applied to metal clusters: evidence of magic numbers
Statistical measures metal clusters magic numbers
2010/4/2
In this work, a shell model for metal clusters up to 220 valence electrons is used to obtain the fractional occupation probabilities of the electronic orbitals. Then, the calculation of a statistical ...
Indifference of Defaultable Bonds with Stochastic Intensity models
Credit Risk model Cox Process HJB equations Indif-ference Pricing Minimal Entropy Measure Finite difference Method
2010/4/27
The utility-based pricing of defaultable bonds in the case of stochastic intensity models of default risk is discussed. The Hamilton-Jacobi- Bellman (HJB) equations for the value functions is derived....

Statistical identification with hidden Markov models of large order splitting strategies in an equity market
Statistical identification hidden Markov models order splitting strategies
2010/4/27
Large trades in a financial market are usually split into smaller parts and traded incrementally over extended periods of time. We address these large trades as hidden orders. In order to identify and...
This article relies on [15] that the author wrote with Gang Tian and Xiaodong Wang. In view of Hamilton's important work on the Ricci flow and Perelman's paper on the Ricci flow where he developes the...
