  4. 22. Renormalization of Lorenz Maps

    Author : Björn Winckler; Marco Martens; Michael Benedicks; Welington de Melo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Analys;

    Abstract : This thesis is a study of the renormalization operator on Lorenz αmaps with a critical point. Lorenz maps arise naturally as first-return maps for three-dimensional geometric Lorenz flows. Renormalization is a tool for analyzing the microscopic geometry of dynamical systems undergoing a phase transition. READ MORE

  5. 23. Traces of Mathematical Facts and Students’ Understanding of the Concept `Quadrilateral´ : An enquiry into young students’ communication

    Author : Eva Juhlin; Maria Johansson; Ewa Bergqvist; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Abstract : Mathematics could be described as a special kind of language, a discourse in which participants communicate abstract concepts. Communication and language are known to be important factors in teaching and learning but little is known about neither communication between students in relation to geometrical concepts, nor what traces of mathematical facts and understanding is incorporated into their communication.

  6. 24. Topics in geometry, analysis and inverse problems

    Author : Hans Rullgård; Mikael Passare; Victor Palamodov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laurent series; Harnack curves; differential equations; tomography; Mathematical logic; Matematisk logik;

    Abstract : The thesis consists of three independent parts.Part I: Polynomial amoebasWe study the amoeba of a polynomial, as de ned by Gelfand, Kapranov and Zelevinsky. A central role in the treatment is played by a certain convex function which is linear in each complement component of the amoeba, which we call the Ronkin function. READ MORE

  7. 25. Numerical methods for wave propagation in solids containing faults and fluid-filled fractures

    Author : Ossian O'Reilly; Jan Nordström; Per Lötstedt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis develops numerical methods for the simulation of wave propagation in solids containing faults and fluid-filled fractures. These techniques have applications in earthquake hazard analysis, seismic imaging of reservoirs, and volcano seismology. A central component of this work is the coupling of mechanical systems.
