    Abstract : We deal with low-dimensional homology and cohomology of current Lie algebras, i.e., Lie algebras which are tensor products of a Lie algebra L and an associative commutative algebra A. READ MORE

  2. 17. Quasi-Lie Algebras and Quasi-Deformations. Algebraic Structures Associated with Twisted Derivations

    University dissertation from Department of Mathematics, Lund University

    Author : Daniel Larsson; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Talteori; fältteori; algebraisk geometri; algebra; gruppteori; Lie Algebras; Quasi-Deformations; Number Theory; field theory; algebraic geometry; group theory; Quasi-Lie Algebras;

    Abstract : This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasi-deformations? to clearly distinguish it from the classical Grothendieck-Schlessinger and Gers-tenhaber deformation schemes. The main difference is that quasi-deformations are not in gene-ral category-preserving, i.e. READ MORE

  4. 19. Tangential Derivations, Hilbert Series and Modules over Lie Algebroids

    University dissertation from Stockholm : Department of Mathematics, Stockholm University

    Author : Yohannes Tadesse; Rolf Källström; Michael Granger; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tangential Derivations; Monomials; Multiplier Ideals; Lie Algebroids; Hilbert series; matematik; Mathematics;

    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.

  5. 20. On the estimation of ligand binding affinities

    University dissertation from Department of Chemistry, Lund University

    Author : Samuel Genheden; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; binding affinities protein-ligand complexes; host-guest complexes; MM GBSA; MM PBSA; LIE; PDLD s-LRA; alchemical methods; sampling; solvation; drug design;

    Abstract : A method to accurately estimate the binding affinity of a small molecule to a receptor would be indispensable in numerous fields. For instance, most drugs exert their action by binding to a macromolecule target. Thus, a lot of time and resources could be saved in drug design by predicting affinities by computer programs.
