Vor einem Tag · Two important examples of Markov processes are the Wiener process, also known as the Brownian motion process, and the Poisson process, which are considered the most important and central stochastic processes in the theory of stochastic processes.
Vor 4 Tagen · The model is expressed as the Black–Scholes equation, a partial differential equation describing the changing price of the option over time; it is derived assuming log-normal, geometric Brownian motion (see Brownian model of financial markets).
Vor 3 Tagen · Abstract: Euclidean branching Brownian motion (BBM) has been intensively studied during many decades by renowned researchers. BBM on hyperbolic space has received less attention. A profound study of Lalley and Sellke (1997) provided insight on the recurrent, resp. transient regimes of BBM on the Poincare' disk. In particular, they determined the Hausdorff dimension of the limit set on the ...
Vor 5 Tagen · Brownian diffusion and thermophoresis are the dominant slip mechanisms when turbulent eddies are absent. Brownian motion is a significant mechanism which impacts fluid suspension and its thermal conductivity. Another attributed factor is the layered structure (interfacial nanolayer) formed between the liquid molecules close to the solid particle surface
Vor einem Tag · Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium ...
Vor 6 Tagen · [Submitted on 9 May 2024] Weak coupling limit of a Brownian particle in the curl of the 2D GFF. Huanyu Yang, Zhilin Yang. In this article, we study the weak coupling limit of the following equation in R2: dXε t = λ^ log 1 ε− −−−√ ωε(Xε t)dt + νdBt, Xε0 = 0.
Vor 2 Tagen · Here, I show that the detected stochastic signal is also consistent in amplitude and frequencies with the Brownian motion of the Sun as a result of its interaction with unmodeled Main-belt asteroids of diameters ≲ 80 less-than-or-similar-to absent 80 \lesssim 80 ≲ 80 km. In § 2, I derive the amplitude and frequencies of the resulting Doppler noise in pulsar timing, and in § 3, I suggest ...
