Nonequilibrium Approach to Bloch-Peierls-Berry Dynamics [PDF]

open access: yes, 2006
We examine the Bloch-Peierls-Berry dynamics under a classical nonequilibrium dynamical formulation. In this formulation all coordinates in phase space formed by the position and crystal momentum space are treated on equal footing.

Dissipative Sturm-Liouville Operators with Transmission Conditions

open access: yesAbstract and Applied Analysis, 2013
In this paper we study dissipative Sturm-Liouville operators with transmission conditions. By using Pavlov’s method (Pavlov 1947, Pavlov 1981, Pavlov 1975, and Pavlov 1977), we proved a theorem on completeness of the system of eigenvectors and associated

A Sharp Liouville Theorem for Elliptic Operators [PDF]

open access: yes, 2010
We introduce a new condition on elliptic operators $L= {1/2}\triangle + b \cdot \nabla $ which ensures the validity of the Liouville property for bounded solutions to $Lu=0$ on $\R^d$. Such condition is sharp when $d=1$.

Fluctuation theorems for quantum master equations [PDF]

open access: yes, 2006
A quantum fluctuation theorem for a driven quantum subsystem interacting with its environment is derived based solely on the assumption that its reduced density matrix obeys a closed evolution equation i.e. a quantum master equation (QME).

A Two Well Liouville Theorem [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2005
Summary: We analyse the structure of approximate solutions to the compatible two-well problem with the constraint that the surface energy of the solution is less than some fixed constant. We prove a quantitative estimate that can be seen as a two-well analogue of the Liouville theorem of \textit{G. Friesecke}, \textit{R. D. James} and \textit{S. Müller}

Fractional Noether's Theorem with Classical and Riemann-Liouville Derivatives

open access: yes, 2012
We prove a Noether type symmetry theorem to fractional problems of the calculus of variations with classical and Riemann-Liouville derivatives. As result, we obtain constants of motion (in the classical sense) that are valid along the mixed classical ...

The Liouville-type theorem for integrable Hamiltonian systems with incomplete flows

open access: yes, 2012
For integrable Hamiltonian systems with two degrees of freedom whose Hamiltonian vector fields have incomplete flows, an analogue of the Liouville theorem is established.

On Cauchy–Liouville-type theorems

open access: yesAdvances in Nonlinear Analysis, 2017
AbstractIn this paper we explore Liouville-type theorems to solutions of PDEs involving the ϕ-Laplace operator in the setting of Orlicz–Sobolev spaces. Our results extend Liouville-type theorems that have been obtained recently.
