    Author : Olivia Constantin; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; Hankel operators; similarity to contractions; atomic decompositions;

    Abstract : Abstract This thesis consists of the following three papers Paper I. Hankel operators on Bergman spaces and similarity to contractions. In this paper we consider Foguel-Hankel operators on vector-valued Bergman spaces. READ MORE

  4. 17. Functions of Generalized Bounded Variation

    Author : Martin Lind; Viktor Kolyada; Peter Oswald; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bounded p-variation; generalized bounded variation; modulus of continuity; function spaces; embeddings; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation.First, we study the functions of bounded p-variation introduced by Wiener in 1924. We obtain estimates of the total p-variation (1.. READ MORE

  5. 18. Holomorphic functions on polydiscs and measures on the distinguished boundary

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

    Abstract : 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. READ MORE

  6. 19. Properties of the Discrete and Continuous Spectrum of Differential Operators

    Author : Andreas Enblom; Ari Laptev; Alexei Ilyin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : This thesis contains three scientific papers devoted to the study of different spectral theoretical aspects of differential operators in Hilbert spaces.The first paper concerns the magnetic Schrödinger operator (i∇ + A)2 in L2(ℝn). READ MORE

  7. 20. Of Imagined and Potential Futures : Speculative Fiction in Southern Africa, 2008-2018

    Author : Joanna Woods; Stefan Helgesson; Marina Kohnen Ludwigs; Adnan Mahmutović; Madhu Krishnan; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Southern Africa; contemporary literature; speculative fiction; short stories; digital; rhetorical studies; narratology; literary field; English; engelska;

    Abstract : This research project explores the rhetorical function of contemporary Anglophone speculative fiction (sf) in southern Africa. Focusing on short fiction produced between 2008 and 2018, the project delineates this literary production both theoretically and historically. READ MORE
