  1. 1. Envelopes of holomorphy for bounded holomorphic functions

    Författare :Ulf Backlund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; holomorphicfunction; boundedholomorphic function; domain of holo¬ morphy; envelope of holomorphy; Gleason’s problem; convex set; plurisubharmonic function; pluripolar set; poly normally convex set;

    Sammanfattning : Some problems concerning holomorphic continuation of the class of bounded holo­morphic functions from bounded domains in Cn that are domains of holomorphy are solved. A bounded domain of holomorphy Ω in C2 with nonschlicht H°°-envelope of holomorphy is constructed and it is shown that there is a point in D for which Glea­son’s Problem for H°°(Ω) cannot be solved.

  4. 3. Convex multicommodity flow problems : a bidual approach

    Författare :Kristoffer Hägglöf; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The topic of this dissertation, within the subfield of mathematics known as optimization, is the development of a new dual ascent method for convex multicommodity flow problems. Convex multicommodity flow problems arize in many different routing problems such as the design of packet switched computer networks and the computation of traffic network equilibria. LÄS MER

  5. 4. Asynchronous First-Order Algorithms for Large-Scale Optimization : Analysis and Implementation

    Författare :Arda Aytekin; Mikael Johansson; Lin Xiao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex; optimization; asynchronous; algorithms; parallel; distributed; large-scale; big data; software; serverless; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER

  7. 5. Performing Punk : Subcultural Authentications and the Positioning of the Mainstream

    Författare :Erik Hannerz; Tora Holmberg; Philip Lalander; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; subculture; punk; mainstream; authentication; style; identity; cultural sociology; ethnography; convex; concave; patterns of meaning; Sociologi; Sociology;

    Sammanfattning : This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic.
