16. Lowdimensional cohomology of current Lie algebras
University dissertation from Stockholm : Department of Mathematics, Stockholm UniversityAbstract : We deal with lowdimensional 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

17. QuasiLie Algebras and QuasiDeformations. Algebraic Structures Associated with Twisted Derivations
University dissertation from Department of Mathematics, Lund UniversityAbstract : This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasideformations? to clearly distinguish it from the classical GrothendieckSchlessinger and Gerstenhaber deformation schemes. The main difference is that quasideformations are not in general categorypreserving, i.e. READ MORE

19. Tangential Derivations, Hilbert Series and Modules over Lie Algebroids
University dissertation from Stockholm : Department of Mathematics, Stockholm UniversityAbstract : Let A/k be a local commutative algebra over a field k of characteristic 0, and T_{A/k} be the module of klinear derivations on A. We study, in two papers, the set of klinear derivations on A which are tangential to an ideal I of A (preserves I), defining an Asubmodule T_{A/k}(I) of T_{A/k}, which moreover is a kLie subalgebra.

20. On the estimation of ligand binding affinities
University dissertation from Department of Chemistry, Lund UniversityAbstract : 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.
