Stationary reflection in extender models

Ernest Schimmerling (2005)

Fundamenta Mathematicae

Similarity:

Working in L[E], we examine which large cardinal properties of κ imply that all stationary subsets of cof(<κ) ∩ κ⁺ reflect.

Linear transformations of locally stationary processes

Jiří Michálek (1989)

Aplikace matematiky

Similarity:

The paper deals with linear transformations of harmonizable locally stationary random processes. Necessary and sufficient conditions under which a linear transformation defines again a locally stationary process are given.

On stationary kinetic systems of Boltzmann type and their fluid limits

Leif Arkeryd (2004)

Banach Center Publications

Similarity:

The first part reviews some recent ideas and L¹-existence results for non-linear stationary equations of Boltzmann type in a bounded domain in ℝⁿ and far from global Maxwellian equilibrium. That is an area not covered by the DiPerna and P. L. Lions methods for the time-dependent Boltzmann equation from the late 1980-ies. The final part discusses the more classical perturbative case close to global equilibrium and corresponding small mean free path limits of fully non-linear stationary...

Stationary states and moving planes

Gerhard Ströhmer (2008)

Banach Center Publications

Similarity:

Most of the paper deals with the application of the moving plane method to different questions concerning stationary accumulations of isentropic gases. The first part compares the concepts of stationarity arising from the points of view of dynamics and the calculus of variations. Then certain stationary solutions are shown to be unstable. Finally, using the moving plane method, a short proof of the existence of energy-minimizing gas balls is given.
