  1. 1. Partial Balayage and Related Concepts in Potential Theory

    Författare :Joakim Roos; Henrik Shahgholian; Björn Gustafsson; Charles Smart; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Partial balayage; equilibrium measure; obstacle problem; divisible sandpile; Riemannian manifold; quadrature domain; Laplacian growth; mother body; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three papers, all treating various aspects of the operation partial balayage from potential theory.The first paper concerns the equilibrium measure in the setting of two dimensional weighted potential theory, an important measure arising in various mathematical areas, e.g. LÄS MER

  3. 2. Living in times of climate change. Weather-related understandings, realities, and entanglements among Guarani people in the Bolivian Chaco

    Författare :Vanesa Martin Galan; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; weather; climate change; entanglement; ontology; coloniality; hybridity; modernity; non-human agents; agriculture; partial connection; radical difference; Guarani people; Bolivia;

    Sammanfattning : Since climate change became an issue of public concern worldwide, the weather has attracted increasing attention and come to stand as a common ground for joint action between Indigenous people and governmental and non-governmental actors in the Bolivian Chaco. Despite becoming a common cause, the management of weather through mitigation and adaptation strategies takes place under ontological differences and power imbalances. LÄS MER

  4. 3. Regularity of multilinear oscillatory integral operators and nonlinear dispersive partial differential equations

    Författare :Aksel Bergfeldt; Wolfgang Staubach; Dorothee Frey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oscillatory integral operators; partial differential equations; Mathematics; Matematik;

    Sammanfattning : We show regularity of multilinear Schrödinger integral operators as well as multilinear oscillatory integrals with connection to dispersive partial differential equations. These results are used to show regularity of a system of nonlinear dispersive partial differential equations... LÄS MER

  5. 4. Partial differential equations and systems related to Morrey spaces

    Författare :Maria Alessandra Ragusa; Alexey Karapetyants; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This PhD thesis deals with the study of well posedness, existence and regularity properties of solutions of partial differential equations and systems. Preparatory to the study of partial differential equations is the action of some integral operators, that are extensively used. LÄS MER

  7. 5. Lp-contractivity of Semigroups Generated by Linear Partial Differential Operators

    Författare :Mikael Langer; Stig Larsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is devoted to the study of contraction semigroups generated by linear partial differential operators. It is shown that linear partial differential operators of order higher than two cannot generate contraction semigroups on (LP)N for p ∈ [1, oo) unless p = 2. LÄS MER
