  3. 2. Ext-algebras of standard modules over quasi-hereditary algebras

    Författare :Markus Thuresson; Julian Külshammer; Pierre-Guy Plamondon; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis concerns the representation theory of a particular class of finite-dimensional algebras, called quasi-hereditary algebras. In particular, it considers two subclasses of quasi-hereditary algebras: dual extension algebras and hereditary algebras. It consists of three papers. LÄS MER

  4. 3. On Stratified Algebras and Lie Superalgebras

    Författare :Anders Frisk; Volodymyr Mazorchuk; Karl-Heinz Fieseler; Steffen Koenig; Uppsala universitet; []
    Nyckelord :Algebra and geometry; Stratified algebras; Lie Superalgebras; Properly stratified algebras; Quasi-hereditary algebras; the queer Lie superalgebra; Kostant s Theorem; Algebra och geometri;

    Sammanfattning : This thesis, consisting of three papers and a summary, studies properties of stratified algebras and representations of Lie superalgebras.In Paper I we give a characterization when the Ringel dual of an SSS-algebra is properly stratified. LÄS MER
