Partial quasimorphisms and quasistates on cotangent bundles, and symplectic homogenization

open access: yesJournal of Modern Dynamics, 2012
Let \(T^*N\) be the cotangent bundle of an \(n\)-dimensional closed oriented manifold \(N\) with the natural symplectic structure and \({\mathcal G}\) the Hamiltonian group with compact support on \(T^*N\). In this paper two families of functions \(\mu_a:{\mathcal G}\to\mathbb{R}\) and \(\zeta_a: C^\infty_c(T^*N)\to \mathbb{R}\), \(a\in H^1(N;\mathbb{R}

Quasistable gradient and hamiltonian systems with a pairwiseinteraction randomly perturbed by wiener processes [PDF]

open access: yesInternational Journal of Stochastic Analysis, 2002
Let \(w_k\) be a sequence of independent standard Wiener processes in \(R^d\), \(x_k\) be a finite or infinite sequence of \(R^d\)-valued stochastic processes that describe the evolution of a set of randomly perturbed pairwise interacting particles. Gradient and Hamiltonian systems of the form \[ dx_k(t)=F_k(t) dt+\sigma dw_k(t) \quad\text{and}\quad d ...

Weak Quasistability and Rajchman measures

open access: yes
It is shown that weak quasistability does not imply power boundedness, but coercive power unbounded operators cannot be weakly quasistable.\ Although a finite measure over the unit disc is a Rajchman measure if and only if the position operator is weakly stable, it is shown that the position operator is weakly quasistable for every finite continuous ...

Mechanisms and Characteristics of Thermodynamically Quasistable Structure Formation in Metals

open access: yesEnvironmental and Climate Technologies
Abstract This paper investigates the processes of thermodynamic pseudostability (metastability) in liquid metals during rapid solidification, a mechanism that results in the formation of an amorphous structure. Established technologies for creating bulk amorphous materials are typically limited to producing only a thin amorphous layer.
