  2. 1. Tangential Derivations, Hilbert Series and Modules over Lie Algebroids

    Author : Yohannes Tadesse; Rolf Källström; Michael Granger; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tangential Derivations; Monomials; Multiplier Ideals; Lie Algebroids; Hilbert series; Mathematics; matematik;

    Abstract : Let A/k be a local commutative algebra over a field k of characteristic 0, and T_{A/k} be the module of k-linear derivations on A. We study, in two papers, the set of k-linear derivations on A which are tangential to an ideal I of A (preserves I), defining an A-submodule T_{A/k}(I) of T_{A/k}, which moreover is a k-Lie subalgebra.

    Abstract : In this thesis we consider regularity properties for solutions to partial differential equations and pseudo-differential equations. The thesis mainly concerns wave-front sets and micro-local properties. READ MORE

  5. 3. Motion Vision Processing in Fly Lobula Plate Tangential Cells

    Author : Yu-Jen Lee; Karin Nordström; Holger Kraap; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hoverflies; EMD; higher order motion; octopamine; cSIFE; figure-ground discrimination; motion vision; lobula plate tangential cells;

    Abstract : Flies are highly visually guided animals. In this thesis, I have used hoverflies as a model for studying motion vision. Flies process motion vision in three visual ganglia: the lamina, the medulla, and the lobula complex. In the posterior part of lobula complex, there are around 60 lobula plate tangential cells (LPTCs). READ MORE
