A Cartier-Gabriel-Kostant structure theorem for Hopf algebroids
Cartier-Gabriel-Kostant structure theorem Hopf algebroids
2011/3/1
In this paper we give an extension of the Cartier-Gabriel-Kostant structure theorem to Hopf algebroids.
A $c_0$ saturated Banach space with tight structure
c0 saturated Banach spaces space of operators saturated norms hereditarily
2011/1/21
It is shown that variants of the HI methods could yield objects closely connected to the classical Banach spaces. Thus we present a new c0 saturated space, denoted as X0,with rather tight structure.
Local structure of the set of steady-state solutions to the 2D incompressible Euler equations
Local structure of the set steady-state solutions 2D incompressible Euler equations
2011/1/21
It is well known that the incompressible Euler equations can be formulated in a very geometric language. The geometric structures provide very valuable insights into the properties of the solutions.

The AKNS Hierarchy Integrability Analysis Revisited: The Vertex Operator Approach and its Lie-Algebraic Structure
the AKNS hierarchy Lax type integrability Lie-algebraic approach
2011/3/2
A regular approach to studying the Lax type integrability of the AKNS hierarchy of nonlinear Lax type integrable dynamical systems in the vertex operator representation is devised.
Based on the proof of Labastida-Mari˜no-Ooguri-Vafa conjecture [6], we derive an infinite product formula for Chern-Simons partition functions, the generating function of quantum slN invariants. ...

A regular approach to studying the Lax type integrability of the AKNS hierarchy of nonlinear Lax type integrable dynamical systems in the vertex operator representation is devised.
Shell structure and orbit bifurcations in finite fermion systems
Shell structure orbit bifurcations finite fermion systems
2011/3/2
We first give an overview of the shell-correction method which was developed by V. M.Strutinsky as a practicable and efficient approximation to the general selfconsistent theory of finite fermion syst...
A Lotka-Volterra model with impulsive effects on the prey and stage structure on the predator
Stage structure Impulsive Global attractivity Permanence
2010/9/21
In this paper, we consider a Lotka-Volterra model with impulsive effects on the prey and stage structure on the predator. We prove that all solutions of the system are uniformly ultimately bounded, su...

2010/12/16
The recently introduced discrete persistent structure extractor (DisPerSE Soubie 2010, paper I) is implemented on realistic 3D cosmological simulations and observed redshift catalogues; it is found th...

In the \positive interest" models of Flesaker and Hughston, the nominal discount bond system is determined by the speci cation of a one-parameter family of positive martingales.
Non-linear Group Actions with Polynomial Invariant Rings and a Structure Theorem for Modular Galois Extensions
Non-linear Group Polynomial Invariant Rings
2010/11/24
Let $G$ be a finite $p$-group and $k$ a field of characteristic $p>0$. We show that $G$ has a \emph{non-linear} faithful action on a polynomial ring $U$ of dimension $n=\mathrm{log}_p(|G|)$ such that...

2010/11/24
Given manifolds $M$ and $N$, with $M$ compact, we study the geometrical structure of the space of embeddings of $M$ into $N$, having less regularity than $\mathcal C^\infty$, quotiented by the group o...
