Summary
The paper presents the nonequilibrium statistical (kinetical) treatment of the Gauss-Markov «external» and self-consistent «intrinsic» fluctuations in an «embedded» plasma system based on the separation and decoupling of the statisticalt and stochastical τ time scales. In the frame of the generalized Gauss-Markov oscillator model, this description yields both the arbitrary kinetic-level decomposition of the statistical distributions and correlations, and Gauss-Markov evolution and momentum equations with coherent structure. The first part of the paper is concerned with both the Gauss-Markov Liouville dynamics and the Gauss-Markov propagators of this «embedded» plasma system.
Riassunto
Questo lavoro presenta il trattamento (cinetico) statistico di non equilibrio delle fluttuazioni di Gauss-Markov «esterne» e «intrinseche» autoconsistenti in un sistema di plasma incluso basato sulla separazione ed il disaccoppiamento delle scale temporali statistichet e stocastiche τ. Nell’ambito del modello di oscillatore generalizzato di Gauss-Markov, questa descrizione genera sia la scomposizione arbitraria del livello cinetico delle distribuzioni statistiche e delle correlazioni, sia le equazioni dell’impulso e di evoluzione di Gauss-Markov con struttura coerente. La prima parte di questo lavoro riguarda sia la dinamica di Gauss-Markov Liouville sia i propagatori di Gauss-Markov di questo sistema di plasma incluso.
Резюме
В этой статье предлагается неравновесное статистическое (кинетическое) рассмотрение Гауссовых-Марковских «внешних» и самосогласованных «внутренних» флуктуаций во «внедренной» плазменной системе. Предложенный подход основан на разделении и развязывании статистическогоt и стохастического τ временных масштабов. В рамках обобщенной Гауссовой-Марковской осцилляторной модели этот формализм дает разложение статистических распределений и корреляций на произвольном кинетическом уровне, а также Гауссову-Марковскую эволюцию и импульсное уравнение с когерентной структурой. Первая часть статьи посвящена Гауссовой-Марковской динамике Лиувилля, а также Гауссовым-Марковским пропагаторам для «внедренной» плазменной системы.
