  1. 1. Infinite dimensional holomorphy in the ring of formal power series : partial differential operators

    Författare :Henrik Petersson; Andrei Khrennikov; Sean Dineen; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Infinite dimensional holomorphy; Formal power series; Fourier-Borel transform; Paley-Wiener theorem; Fischer decomposition; Fischer pair; Fock space; Cauchy-Problem; Kergin operator; PDE-preserving; Pseudo-differential operators.; MATHEMATICS; MATEMATIK;

    Sammanfattning : We study holomorphy in the ring of formal power series in an infinite number of variables. Thus we restrict our study to (infinite dimensional) holomorphy on sequence spaces and we show that we obtain a rich theory without requiring any topological structure on the domain space. We make a comprehensive PDO-study for the spaces under consideration. LÄS MER

  5. 4. Sequential convergence for functions and operators

    Författare :Jeanette Silfver; Mårten Gulliksson; Anders Holmbom; Nils Svanstedt; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homogenization; two-scale convergence; G-convergence; H-convergence; partial differential equations; functional analysis; heterogeneous media; MATHEMATICS; MATEMATIK;

    Sammanfattning : The mathematical discipline homogenization theory is closely related to convergence issues. In this thesis different types of convergence are studied and put in relation to each other. We consider the classical concepts of G- and H-convergence and compensated compactness. LÄS MER

  7. 5. Attention and Self-regulation in Infancy and Toddlerhood : The Early Development of Executive Functions and Effortful Control

    Författare :Maria Johansson; Gustaf Gredebäck; Gunilla Bohlin; Sandra Anne Wiebe; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Executive functions; Effortful control; Sustained attention; Infancy; Psychology; Psykologi;

    Sammanfattning : Executive functions are higher-order cognitive functions underlying self-regulation of behavior. That is, executive functions make it possible to resolve internal conflicts and behave according to future goals rather than acting on sudden impulses or going on automatic. LÄS MER
