  1. 1. Free loop spaces, Koszul duality and A-infinity algebras

    Författare :Kaj Börjeson; Alexander Berglund; Pascal Lambrechts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Koszul duality; free loop spaces; a-infinity algebras; BV-algebras; string topology; Mathematics; matematik;

    Sammanfattning : This thesis consists of four papers on the topics of free loop spaces, Koszul duality and A∞-algebras. In Paper I we consider a definition of differential operators for noncommutative algebras. This definition is inspired by the connections between differential operators of commutative algebras, L∞-algebras and BV-algebras. LÄS MER

  4. 3. Stable invariants of some topological moduli spaces

    Författare :Erik Lindell; Dan Petersen; Alexander Berglund; Andrew Putman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moduli spaces; mapping class groups; stable invariants; matematik; Mathematics;

    Sammanfattning : This thesis consists of three papers, treating stability phenomena in various automorphism groups in topology. In Papers I and III, we study the group (co)homology of certain mapping class groups of surfaces and graphs, or their respective Torelli subgroups, while the subject of Paper II is homotopy automorphisms of higher-dimensional spaces and manifolds.

  5. 4. On Autonomous Deployment of Micro Aerial Field Vehicles

    Författare :Sina Sharif Mansouri; George Nikolakopoulos; António Pedro Aguiar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In this thesis, I am going to investigate the control, navigation and path planning frame-works forMicro Aerial Vehicles (MAVs), both mathematically and algorithmically. Inorder to deploy them in challenging real life applications and with a main focus on theunderground mine navigation and wind turbine inspection. LÄS MER
