  1. 21. Skew-symmetric matrix pencils : stratification theory and tools

    Författare :Andrii Dmytryshyn; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

  2. 22. Advances in Functional Decomposition: Theory and Applications

    Författare :Andrés Martinelli; Elena Dubrova; Jon Muzio; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer science; electronic system design; Boolean decomposition; binary decision diagram; logic synthesis; graph algorithm; Computer science; Datavetenskap;

    Sammanfattning : Functional decomposition aims at finding efficient representations for Boolean functions. It is used in many applications, including multi-level logic synthesis, formal verification, and testing. This dissertation presents novel heuristic algorithms for functional decomposition. LÄS MER

  3. 23. Representation matters in cyclic proof theory

    Författare :Dominik Wehr; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Logic; Cyclic Proof Theory;

    Sammanfattning : Cyclic proof systems allowderivations whose underlying structure is a finite graph, rather than a well-founded tree. The soundness of cyclic proofs is usually ensured by imposing additional conditions beyond well-formedness. LÄS MER

  5. 25. Topics in discrete random structures

    Författare :Anders Martinsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; First--passage percolation; Cartesian power graph; third moment argument; jigsaw puzzle; shotgun assembly; monotone paths; non-Markovian coupling; high dimension; coupling inequality; monotone paths;

    Sammanfattning : This thesis presents four papers on problems in discrete probability. A common theme of the articles is to take some class of discrete structures, impose some randomness, and then consider what happens asymptotically as the size of the structure tends to infinity. LÄS MER
