  2. 6. The Dirac Operator; From Numerics to the Theory of G-convergence

    Author : Hasan Almanasreh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dirac operator; spuriousity; cubic Hermitian; stability parameter; G-convergence; ¡-convergence; spectral measure; quadratic form; stability parameter;

    Abstract : We consider two main issues concerning the Dirac operator, the first is widely known as the appearance of spurious eigenvalues within the spectrum. The second is the study of the asymptotic behavior of the eigenvalues for a family of Dirac operators with oscillatory potential added to the Coulomb-Dirac Hamiltonian. READ MORE

  4. 7. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators

    Author : Liselott Flodén; Anders Holmbom; Nils Svanstedt; Mårten Gulliksson; Björn Birnir; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; G-convergence; Homogenization; Multiscale convergence; Two-scale convergence; Monotone opertors; Functional analysis; Partial differential equations; Mathematical analysis; Analys;

    Abstract : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. READ MORE

  5. 8. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration

    Author : Martin E. Gustafsson; Roger Bivand; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Economic geography; economic growth; regional convergence; migration; spatial statistics; spatially correlated errors; geographical dependence; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Abstract : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.

  6. 9. Conditional Subgradient Methods and Ergodic Convergence in Nonsmooth Optimization

    Author : Ann-Brith Strömberg; Vladimir F. Dem'yanov; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ergodic convergence; nonsmooth optimization; primal convergence; subgradient methods; conditional subgradient; Convex programming; Lagrangean relaxation;

    Abstract : The topic of the thesis is subgradient optimization methods in convex, nonsmooth optimization. These methods are frequently used, especially in the context of Lagrangean relaxation of large scale mathematical programs where they are remarkably often able to quickly identify near-optimal Lagrangean dual solutions.

  7. 10. Mediatized tourism : The convergence of media and tourism performances

    Author : Maria Månsson; Institutionen för tjänstevetenskap; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sense of place; Popular culture; Performance; Mediatization; Film tourism; Destination marketing; Convergence; The Da Vinci Code;

    Abstract : Popular culture and tourism are intertwining. The use of film and literature amongst destination marketing organisations is a global trend, but how can we understand this phenomenon and all the processes involved? Up to now popular culture and tourism have been researched mainly from a single media perspective. READ MORE
