    • Central cohomology operations and K-theory 

      Gálvez Carrillo, Maria Immaculada; Whitehouse, Sarah (2014-04-16)
      Article
      Accés obert
      For stable degree 0 operations, and also for additive unstable operations of bidegree (0, 0), it is known that the centre of the ring of operations for complex cobordism is isomorphic to the corresponding ring of connective ...

    • Results on the Spinc-genus 

      Zampa, Sarah Juliet (Universitat Politècnica de Catalunya, 2020-10)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      In this work, we study manifolds with a Spin-c-structure, and give results on a Spin-c-genus derived from the Witten genus. We also implement codes in order to compute this genus on usual manifolds.

    • Topological quantum field theories 

      Alsina Oriol, Guillem (Universitat Politècnica de Catalunya, 2015-05)
      Treball Final de Grau
      Accés obert
      The aim of this work is to explain what a topological quantum field theory (TQFT) is and the relation between TQFTs in dimension 2 and Frobenius algebras. More precisely, it is shown that there exists an equivalence of ...
