  1. 1. Physics from Wholeness : Dynamical Totality as a Conceptual Foundation for Physical Theories

    Författare :Barbara Piechocinska; Claes-Göran Granqvist; Erik Sjöqvist; Laszlo Kish; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; wholeness; elementary embedding; left-distributivity; braids; special braids; entropy; Temperley-Lieb algebra; von Neumann algebra; Potts model; Fysik; Physics; Fysik; fasta tillståndets fysik; Solid State Physics;

    Sammanfattning : Motivated by reductionism's current inability to encompass the quantum theory we explore an indivisible and dynamical wholeness as an underlying foundation for physics. After reviewing the role of wholeness in the quantum theory we set a philosophical background aiming at introducing an ontology, based on a dynamical wholeness. LÄS MER

  2. 2. The Diamond Lemma for Power Series Algebras

    Författare :Lars Hellström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; diamond lemma; power series algebra; Gröbner basis; embedding into skew fields; archimedean element in semigroup; q-deformed Heisenberg--Weyl algebra; polynomial degree; ring norm; Birkhoff orthogonality; filtered structure; Matematisk analys; Mathematical analysis; Analys; Mathematics; matematik;

    Sammanfattning : The main result in this thesis is the generalisation of Bergman's diamond lemma for ring theory to power series rings. This generalisation makes it possible to treat problems in which there arise infinite descending chains. LÄS MER

  3. 3. Holomorphic functions on polydiscs and measures on the distinguished boundary

    Författare :Linus Bergqvist; Alan Sola; Emmanuel Fricain; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex variables; Holomorphic functions; Polydiscs; matematik; Mathematics;

    Sammanfattning : This thesis consists of four papers, treating holomorphic functions defined on polydiscs, operators acting on spaces of such functions, and related measures on the n-torus. In paper I we study containment of rational inner functions, or RIFs for short, in Dirichlet type spaces on the unit polydisc D^n. LÄS MER

  4. 4. Intrinsic Formation and Macroscopic Intervention in Multi-agent Systems

    Författare :Silun Zhang; Xiaoming Hu; Johan Karlsson; Jorge Goncalves; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attitude control; agents and autonomous systems; distributed control; formation control; nonlinear systems; moment based modelling; large- scale systems; reduced order modeling; nonlinear system identification; Mathematics; Matematik;

    Sammanfattning : In this dissertation, we study two problems within the field of the multi-agent systems theory. One is the formation control for multiple reducedattitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. LÄS MER
