  2. 21. Random Graph and Growth Models

    Author : Sebastian Rosengren; Maria Deijfen; Pieter Trapman; Tatyana Turova; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; matematisk statistik;

    Abstract : Random graphs is a well-studied field of probability theory, and have proven very useful in a range of applications — modeling social networks, epidemics, and structures on the Internet to name a few. However, most random graphs are static in the sense that the network structure does not change over time. READ MORE

  4. 22. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model

    Author : Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; Discrete mathematics; Diskret matematik;

    Abstract : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. READ MORE

  5. 23. Aspects of Spatial Random Processes

    Author : Olle Häggström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; subshift of finite type; measure of maximal entropy; Ising model; Gibbs measure; uniform spanning tree; first passage percolation; asymptotic shape; first passage percolation;

    Abstract : This thesis consists of five papers dealing with various aspects of spatial random processes. In the first three papers the main focus is on a special class of such processes, namely measures of maximal entropy for subshifts of finite type. READ MORE

  6. 24. Statistical Inference of Information in Networks : Causality and Directed Information Graphs

    Author : Sina Molavipour; Mikael Skoglund; Deniz Gündüz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. READ MORE

  7. 25. Complex patterns : from physical to social interactions

    Author : Andreas Grönlund; Petter Minnhagen; Hawoong Jeong; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex networks; collective dynamics; statistical physics; random graphs; Statistical physics; Statistisk fysik;

    Abstract : Interactions are what gives us the knowledge of the world around us. Interactions on all levels may fundamentally be seen as an exchange of information and a possible response of the same. Whether it is an electron in an electrical field or a handsome dude in a bar responding to a flirtation---interactions make things happen. READ MORE
