    • The Berkovits complex and semi-free extensions of Koszul algebras 

      Gálvez Carrillo, Maria Immaculada; Gorbounov, V.; Shaikh, Zain; Tonks, Andrew (2015-08-18)
      Report de recerca
      Accés obert
      In his extension of W. Siegel's ideas on string quantization, N. Berkovits made several observations which deserve further study and development. Indeed, interesting accounts of this work have already appeared in the ...

    • Thomason cohomology of categories 

      Gálvez Carrillo, Maria Immaculada; Neumann, Frank; Tonks, Andrew (2013)
      Article
      Accés obert
      We investigate cohomology and homology theories of categories with general coefficients given by functors on simplex categories first studied by Thomason. These generalize Baues–Wirsching cohomology and homology of a small ...
    • Thomason cohomology of categories 

      Gálvez Carrillo, Maria Immaculada; Tonks, Andrew; Neumann, Frank (2012-08)
      Report de recerca
      Accés obert
      We introduce cohomology and homology theories for small categories with general coefficient systems from simplex categories first studied by Thomason. These theories generalize at once Baues-Wirsching cohomology and homology ...
    • Three Hopf algebras and their common simplicial and categorical background 

      Gálvez Carrillo, Maria Immaculada; Kaufmann, Ralph L.; Tonks, Andrew (2016-07)
      Report de recerca
      Accés obert
      We consider three a priori totally different setups for Hopf algebras from number theory, mathematical physics and algebraic topology. These are the Hopf algebras of Goncharov for multiple zeta values, that of Connes--Kreimer ...
