Strong law of large numbers for supercritical superprocesses under second moment condition.
second moment but satisfying some weaker finite moment condition. For
any locally compact unimodular group G and any positive function :G→
[0,+∞], we introduce a function G, which describes the ...
Optimal linear static control with moment and yield objectives
Linear static control gaussian distribution convex optimization
2015/8/11
This report describes how to optimize linear static control problems involving first and second moments and yield objectives for Gaussian distributions. These problems can be cast as second-order cone...
High Order Moment Closure with Global Hyperbolicity of Vlasov-Maxwell Equations
Moment closure Vlasov-Maxwell equation Boltzmann equation Ex-tended magnetohydrodynamics
2014/9/26
In this paper, we derive the extended magnetohydrodynamic models based on the
moment closure of the Vlasov-Maxwell equation. We adopt the Grad type moment
expansion which was firstly proposed in [12...

Hyperbolicity of 13-Moment System hyperbolicity region
2014/9/26
We point out that the thermodynamic equilibrium is not an interior point of the
hyperbolicity region of Grad’s 13-moment system. With a compact expansion of the
phase density, which is compacter tha...

2011/9/21
Abstract: The main objective of this article is to study the asymptotic behavior of Salie sums over arithmetic progressions. We deduce from our asymptotic formula that Salie sums possess a bias of bei...
Uniform moment bounds of multi-dimensional functions of discrete-time stochastic processes

2011/9/20
Abstract: We establish conditions for uniform $r$-th moment bound of certain $\R^d$-valued functions of a discrete-time stochastic process taking values in a general metric space. The conditions inclu...

2011/9/2
Abstract: This short note concerns the possible singular behaviour of moment generating functions of finite measures at the boundary of their domain of existence. We look closer at Example 7.3 in O. B...

2011/3/2
We analyze the phase equilibria of systems of polydisperse hydrocar-bons by means of the recently introduced moment method. Hydrocarbons are modelled with the Soave-Redlick-Kwong and Peng-Robinson equ...

For geometries with a closed three-form we briefly overview the notion of multimoment maps. We then give concrete examples of multi-moment maps for homogeneous hypercomplex and nearly K¨ahler manifold...
