  1. 1. Effective Domains and Admissible Domain Representations

    Författare :Göran Hamrin; Viggo Stoltenberg-Hansen; Erik Palmgren; Dieter Spreen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Logic; symbolic and mathematical; domain theory; admissible domain representation; cartesian closure; effective domains; κ-sequential space; limit space; Matematisk logik; Mathematics; Matematik; Mathematical logic;

    Sammanfattning : This thesis consists of four papers in domain theory and a summary. The first two papers deal with the problem of defining effectivity for continuous cpos. LÄS MER

  3. 2. 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. Towards practical and provable domain adaptation

    Författare :Adam Breitholtz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Privileged information; Domain adaptation; Generalization; PAC-Bayes;

    Sammanfattning : One of the most central questions in statistical modeling is how well a model will generalize. Absent strong assumptions we find that this question is difficult to answer in a meaningful way. In this work we seek to increase our understanding of the domain adaptation setting through two different lenses. LÄS MER

  5. 4. Fuzzy Set Theory Applied to Make Medical Prognoses for Cancer Patients

    Författare :Hang Zettervall; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fuzzy set theory; the Mamdani fuzzy control system; the Sugeno controller; fuzzy c-means clustering analysis; point set approximation; linguistic models; the 2-tuple linguistic representations; the hesitant fuzzy linguistic term sets;

    Sammanfattning : As we all know the classical set theory has a deep-rooted influence in the traditional mathematics. According to the two-valued logic, an element can belong to a set or cannot. In the former case, the element’s membership degree will be assigned to one, whereas in the latter case it takes the zero value. LÄS MER
