  2. 1. Hopf Invariants in Real and Rational Homotopy Theory

    Author : Felix Wierstra; Alexander Berglund; Urtzi Buijs; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rational homotopy theory; Real homotopy theory; operads; Hopf invariants; Mathematics; matematik;

    Abstract : In this thesis we use the theory of algebraic operads to define a complete invariant of real and rational homotopy classes of maps of topological spaces and manifolds. More precisely let f,g : M -> N be two smooth maps between manifolds M and N. READ MORE

  4. 2. Modeling and Model Reduction by Analytic Interpolation and Optimization

    Author : Giovanna Fanizza; Anders Lindquist; György Michaletzky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytic Interpolation theory with a degree constraint; rational covariance extension problem; spectral estimation; model reduction; optimization; passive system; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. READ MORE

  5. 3. Topological Phases of Non-Hermitian physics

    Author : Lukas Rødland; Maria Hermanns; Jorge Cayao; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : Non-Hermitian physics has introduced phenomena like the skin effect and exceptional points, challenging traditional views of topological phases. This thesis contrasts two classification frameworks for non-Hermitian systems. READ MORE

  6. 4. Sketches of Noncommutative Topology

    Author : Alexey Kuzmin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis thematically divided into two parts. In the first part we are mastering C*-isomorphism problem by using various techniques applied to different examples of noncommutative algebraic varieties. READ MORE
