  1. 1. Structure and representations of certain classes of infinite-dimensional algebras

    Författare :Brendan Frisk Dubsky; Volodymyr Mazorchuk; Martin Herschend; Rolf Farnsteiner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; infinite-dimensional algebras; representation theory; category O; koszul; koszulity; injections; dihedral; preprojective; young lattice; Mathematics; Matematik;

    Sammanfattning : We study several infinite-dimensional algebras and their representation theory. In Paper I, we study the category O for the (centrally extended) Schrödinger Lie algebra, which is an analogue of the classical BGG category O. We decompose the category into a direct sum of "blocks", and describe Gabriel quivers of these blocks. LÄS MER

  3. 2. Topics on Harmonic analysis and Multilinear Algebra

    Författare :Mahdi Hormozi; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Generalized bounded variation; Helly s theorem; Modulus of variation; Generalized Wiener classes; Symmetry classes of tensors; Orthogonal basis; Brauer symmetry classes of tensors; Multilinear singular integrals; weighted norm inequalities; weighted bounds; local mean oscillation; Lerner s formula; Brauer symmetry classes of tensors;

    Sammanfattning : The present thesis consists of six different papers. Indeed, they treat three different research areas: function spaces, singular integrals and multilinear algebra. In paper I, a characterization of continuity of the $p$-$\Lambda$-variation function is given and Helly's selection principle for $\Lambda BV^{(p)}$ functions is established. LÄS MER

  4. 3. Structure-activity studies of novel colchicine analogs

    Författare :Håkan Bladh; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : Colchicine, a well-known alkaloid isolated from Colchicum autumnale, interferes with microtubule growth and, therefore affects mitosis and other microtubule dependent functions. We have been interested in the structural requirements of colchicine for tubulin recognition. LÄS MER

  5. 4. Accurate Force Fields for Spectroscopic Studies of Protein–Ligand Interactions and Self-Assembly Structures

    Författare :Yogesh Todarwal; Patrick Norman; Daniel Escudero; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Dynamics Simulations; Force Field Parametrization; Density Functional Theory; Host-Guest Chemistry; Self-Assembly Systems; Neurodegenerative Diseases; Supramolecular Chemistry; Fluorescent Ligands; Oligothiophenes; Cyclonaphthodithiophene Diimides; Sulfonimidamide Organogelators; Helicenes.; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

    Sammanfattning : The computational prediction of complex molecular behaviors is an essen- tial component of modern chemistry, as it provides a faster and more cost- effective way to explore molecular interactions that may be difficult or even impossible to study experimentally. Molecular dynamics (MD) simulations of- ten serve as a valuable tool for such predictions; however, their accuracy is inherently dependent on the force field (FF) parameters employed. LÄS MER
