  • Comparing Grothendieck-Witt Groups of a Complex Variety to its Real Topological K-Groups 

    Zibrowius, Marcus (Department of Pure Mathematics and Mathematical Statistics, University of Cambridge, 2009-01)
    On a complex variety X, two different approaches to K-theory are available: the algebraic K-theory of the variety, and the topological K-theory of the underlying topological space. In this context, the algebraic variant ...

  • Witt groups of complex varieties 

    Zibrowius, Marcus (University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsTrinity Hall, 2011-07-12)
    The thesis Witt Groups of Complex Varieties studies and compares two related cohomology theories that arise in the areas of algebraic geometry and topology: the algebraic theory of Witt groups, and real topological K-theory. ...
