  2. 1. Classification of Normal Discrete Kinetic Models

    University dissertation from Karlstad : Karlstad University

    Author : Mirela Christina Vinerean; Mirela Vinerean-Bernhoff; Karlstads universitet.; Karlstads universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; Matematik; Mathematics; Kinetic theory; discrete kinetic velocity models; conservation laws;

    Abstract : “In many interesting papers on discrete velocity models (DVMs), authors postulate from the beginning that the finite velocity space with "good" properties is given and only after this step they study the Discrete Boltzmann Equation. Contrary to this approach, our aim is not to study the equation, but to discuss all possible choices of finite phase spaces (sets) satisfying this type of "good" restrictions. READ MORE

  7. 5. Harmonic measures

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Jonatan Vasilis; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; harmonic measure; square root of the Poisson kernel; Hardy space; p-Laplace operator; random walk; regular tree; discrete minimal thinness;

    Abstract : This thesis uses both analytic and probabilistic methods to study continuous and discrete problems. The main areas of study are the asymptotic properties of p-harmonic measure, and various aspects of the square root of the Poisson kernel.Fix a domain and a boundary point, subject to certain regularity conditions.
