  1. 1. Portfolio Optimization Problems with Cardinality Constraints

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Abolgasem Esmaeily; Felix Loge; [2023]
    Nyckelord :Portfolio Optimization; Modern Portfolio Theory MPT • Mixed Integer Programming MIP ; Efficient Frontier; Cardinality Constraints; Daily Returns; Expected Returns; Asset Allocation; Diversification;

    Sammanfattning : This thesis analyzes the mean variance optimization problem with respect to cardinalityconstraints. The aim of this thesis is to figure out how much of an impact transactionchanges has on the profit and risk of a portfolio. We solve the problem by implementingmixed integer programming (MIP) and solving the problem by using the Gurobi solver. LÄS MER

  3. 2. Abstract Logics and Lindström's Theorem

    Kandidat-uppsats, Uppsala universitet/Algebra, logik och representationsteori

    Författare :Niclas Bengtsson; [2023]
    Nyckelord :model theory; abstract model theory; logic; mathematical logic; abstract logic; Lindström s Theorem; infinitary logics; strength of logics; cardinality quantifiers; modellteori; abstrakt modellteori; logik; matematisk logik; abstrakt logik; Lindströms sats;

    Sammanfattning : A definition of abstract logic is presented. This is used to explore and compare some abstract logics, such as logics with generalised quantifiers and infinitary logics, and their properties. Special focus is given to the properties of completeness, compactness, and the Löwenheim-Skolem property. LÄS MER

  4. 3. Erdős-Kaplansky Satsen

    Kandidat-uppsats, Uppsala universitet/Algebra, logik och representationsteori

    Författare :Edvin Lundin; [2023]
    Nyckelord :dualspace; cardinality; dimension; infinite-dimensional; vectorspace; dualrum; kardinalitet; dimension; oändlig-dimensionell; oändlig-dimensionella; vektorrum;

    Sammanfattning : Inom linja ̈r algebra har varje vektorrum ett s ̊a kallat dualrum, vilket är ett vektorrum bestående av alla linjära funktioner från det ursprungliga rummet till sin kropp. Att beräkna dimensionen av ett dualrum tillhörande ett ändlig-dimensionellt vektorrum är relativt enkelt, för oändlig-dimensionella vektorrum är det mer komplicerat.

  5. 4. A Study on Poset Probability

    Kandidat-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Albin Jaldevik; [2022]
    Nyckelord :Discrete mathematics; Order theory; Combinatorics; Partially ordered set; Poset; Linear extension; Topological sorting; Probability; Partition; Young diagram;

    Sammanfattning : Let be a finite poset (partially ordered set) with cardinality . A linear extension of is an order-preserving bijection : , that is, if in then . We define the poset probability as the proportion of linear extensions where . We are primarily interested in for incomparable elements . LÄS MER

  7. 5. A systematic mapping study of mapping modelling languages

    Magister-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Marija Popovic; Amila Cizmic; [2022]
    Nyckelord :mapping; mapping model; mapping metamodel; mapping language;

    Sammanfattning : Context - Various research teams, as well as individual researchers, have investigated mapping modelling languages. However, systematic studies that provide a structured overview of this research on this topic have not been conducted. It is noticeable that this leaves a big gap in the context of a modelling language. LÄS MER
