  2. 1. Index theory in geometry and physics

    Author : Magnus C H T Goffeng; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

    Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

  4. 2. Cost-effectiveness analysis of health technologies when evidence is scarce

    Author : Thor-Henrik Brodtkorb; Jan Persson; Martin Henriksson; Per Carlsson; Ken Stein; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health and medical services in society; Hälso- och sjukvård i samhället;

    Abstract : Given the increasing pressures on health care budgets, economic evaluation is used in many countries to assist decision-making regarding the optimal use of competing health care technologies. Although the standard methods of estimating cost-effectiveness underpinning these decisions have gained widespread acceptance, concerns have been raised that many technologies would not be considered for funding, due to scarcity of evidence.

  5. 3. On Clustering of Random Points in the Plane and in Space

    Author : Marianne Månsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geometric probability; integral geometry; convex sets; random intersections; mixed volumes; scan statistics; Poisson approximation; Stein-Chen method; convergence of point processes; scan statistics;

    Abstract : If n points are independently and uniformly distributed in a large rectangular parallelepiped, A in Rd, d =2,3, they may possibly aggregate in such a way that they are contained in some translate of a given convex set C in A. If the points are replaced by copies of C, these translated sets may have a non-empty intersection. READ MORE

  6. 4. Holomorphic extension and schlichtness on tube manifolds

    Author : Suprokash Hazra; Egmont Porten; Cornelia Schiebold; Andreas Lind; Per Åhag; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Envelopes of holomorphy; truncated tube domains; holomorphic extension; Bochner tube; manifold; schlichtness;

    Abstract : We first investigate the holomorphic extension of some classical and accessible classes of domains in $\mathbb{C}^n$ to know to what extent their envelopes are constructive. We give alternative proofs to some of the classical theorems using only first-principle arguments and without involving higher Stein geometry. READ MORE

  7. 5. Maximal theorems and Calderón-Zygmund type decompositions forthe fractional maximal function

    Author : Evgeny Kuznetsov; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : A very significant role in the estimation of different operators in analysis is played by the Hardy-Littlewood maximal function. There are a lot of papers dedicated to the study of properties of it, its variants, and their applications. READ MORE
