      For stable degree zero 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 ...

      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 ...
    • Homotopy Gerstenhaber structures and vertex algebras 

      Gálvez Carrillo, Maria Immaculada; Gorbounov, V.; Tonks, Andrew (2010)
      Article
      Accés obert
      We provide a simple construction of a G∞-algebra structure on an important class of vertex algebras V, which lifts the Gerstenhaber algebra structure on BRST cohomology of V introduced by Lian and Zuckerman. We outline two ...
    • Infinite sums of Adams operations and cobordism. 

      Gálvez Carrillo, Maria Immaculada; Whitehouse, Sarah (2005)
      Article
      Accés obert
      The elements of various algebras of stable degree zero operations in p-local K-theory can be described explicitly as certain infinite sums of Adams operations [11, 9]. Here we show how to make sense of the same expressions ...
    • Optimising the topological information of the A8-persistence groups 

      Belchi Guillamon, Francisco (2019)
      Article
      Accés obert
      Persistent homology typically studies the evolution of homology groups Hp(X) (with coefficients in a field) along a filtration of topological spaces. A8-persistence extends this theory by analysing the evolution of subspaces ...
    • SAQ: semi-algebraic quartet reconstruction 

      Casanellas Rius, Marta; Fernández Sánchez, Jesús; Garrote López, Marina (2021-01-01)
      Article
      Accés obert
      We present the phylogenetic quartet reconstruction method SAQ (Semi-Algebraic Quartet reconstruction). SAQ is consistent with the most general Markov model of nucleotide substitution and, in particular, it allows for rate ...
