Wiener process

Reflected Brownian motion

In probability theory, reflected Brownian motion (or regulated Brownian motion, both with the acronym RBM) is a Wiener process in a space with reflecting boundaries. In the physical literature, this process describes diffusion in a confined space and it is often called confined Brownian motion. For example it can describe the motion of hard spheres in water confined between two walls. RBMs have been shown to describe queueing models experiencing heavy traffic as first proposed by Kingman and proven by Iglehart and Whitt. (Wikipedia).

Evgeni Dimitrov (Columbia) -- Towards universality for Gibbsian line ensembles

Gibbsian line ensembles are natural objects that arise in statistical mechanics models of random tilings, directed polymers, random plane partitions and avoiding random walks. In this talk I will discuss a general framework for establishing universal KPZ scaling limits for sequences of Gib

Hybrid zones are narrow regions in which two genetically distinct populations come together and interbreed, resulting in hybrids. They may be maintained by an abrupt change in the environment or because of natural selection against the hybrids, in which case the location of the zone can ch

Refraction (1 of 5) What is Refraction? An Explanation

Refraction, A conceptual qualitative explanation. Refraction is the change in direction of a ray of light as it passes from one medium to another. The amount of refraction is determined by the index of refraction of the media and the angle of incidence. For light, refraction follows Snell
