  1. 21. Consensus Algorithms for Trees and Strings

    Författare :Jesper Jansson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical analysis; computational complexity; Approximation algorithm; labeled tree; lowest common ancestor constraint; maximum agreement subtree; alignment between trees; clustering; Computer science; Hamming metric; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : This thesis studies the computational complexity and polynomial-time approximability of a number of discrete combinatorial optimization problems involving labeled trees and strings. The problems considered have applications to computational molecular biology, pattern matching, and many other areas of computer science. LÄS MER

  3. 22. Measures of Freedom of Choice

    Författare :Karin Enflo; Erik Carlson; Thomas Anderberg; Martin van Hees; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Freedom of Choice; Measure; Choice Set; Diversity; Cardinality; Evenness; Decision Theory; Metric Space; Practical Philosophy; Praktisk filosofi;

    Sammanfattning : This thesis studies the problem of measuring freedom of choice. It analyzes the concept of freedom of choice, discusses conditions that a measure should satisfy, and introduces a new class of measures that uniquely satisfy ten proposed conditions. LÄS MER

  7. 25. Reproducing kernels and potential theory for the Bergman spaces

    Författare :Yolanda Perdomo Gallipoli; Matematikcentrum; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; weighted biharmonic Green function Gaussian curvature; Naturvetenskap; harmonic compensator; Natural science; weighted super-biharmonic function; potential metric; mean value property; weighted Bergman kernel;

    Sammanfattning : The role of weighted biharmonic Green functions in weighted Bergman spaces was first studied in the beginning of the 50's by Paul Garabedian. In 1951 he showed that they are closely related to reproducing kernel functions of weighted Bergman spaces. LÄS MER
