  1. 1. Prop profiles of compatible Poisson and Nijenhuis structures

    Author : Henrik Strohmayer; Sergei Merkulov; Gilles Halbout; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Koszul duality; resolutions; props; operads; compatible structures; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : A prop profile of a differential geometric structure is a minimal resolution of an algebraic prop such that representations of this resolution are in one-to-one correspondence with structures of the given type. We begin this thesis with a detailed account of the algebraic tools necessary to construct prop profiles; we treat operads and props, and resolutions of these through Koszul duality. READ MORE

  2. 2. On Face Vectors and Resolutions

    Author : Afshin Goodarzi; Anders Björner; Volkmar Welker; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis consist of the following three papers.Convex hull of face vectors of colored complexes. In this paper we verify a conjecture by Kozlov (Discrete ComputGeom18(1997) 421–431), which describes the convex hull of theset of face vectors ofr-colorable complexes onnvertices. READ MORE

  3. 3. Residue Currents and their Annihilator Ideals

    Author : Elizabeth Wulcan; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : residue currents; Bochner-Martinelli formula; ideals of holomorphic functions; monomial ideals; coherents sheaves; free resolutions of modules; cellular resolutions; coherents sheaves;

    Abstract : This thesis presents results in multidimensional residue theory. From a generically exact complex of locally free analytic sheaves $\mathcal C$ we construct a vector valued residue current $R^\mathcal C$, which in a sense measures the exactness of $\mathcal C$. READ MORE

  4. 4. Ruthenium-Catalyzed Hydrogen Transfer Reactions : Mechanistic Studies and Chemoenzymatic Dynamic Kinetic Resolutions

    Author : Madeleine Warner; Jan-Erling Bäckvall; Andreas Pfaltz; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Hydrogen transfer; ruthenium catalysis; kinetic resolution; dynamic kinetic resolution; racemization; asymmetric synthesis; Organic Chemistry; organisk kemi;

    Abstract : The main focus of this thesis lies on transition metal-catalyzed hydrogen transfer reactions. In the first part of the thesis, the mechanism for racemization of sec-alcohols with a ruthenium complex, Ru(CO)2Cl(η5-C5Ph5) was studied. READ MORE
