      Marmaneu Tarín, David Universitat Jaume I (2018-10-29)
      La nación o el nacionalismo son conceptos que en la sociedad actual apenas se cuestionan, ya que se creen bastante consolidados y su definición nos puede parecer bastante obvia. Pues una nación es básicamente un país con ...

    • openAccess   Newton–Okounkov Bodies of Exceptional Curve Plane Valuations Non-positive at Infinity 

      Galindo, Carlos; Montserrat Delpalillo, Francisco José; Moyano-Fernández, Julio José; Nickel, Matthias Springer (2018-11-04)
      In this note we announce a result determining the Newton–Okounkov bodies of the line bundle OP2(1) with respect to exceptional curve plane valuations non-positive at infinity.

    • openAccess   Newton–Okounkov bodies of exceptional curve valuations 

      Galindo, Carlos; Moyano-Fernández, Julio José; Monserrat, Francisco; Nickel, Matthias European Mathematical Society (2020-03-20)
      We prove that the Newton–Okounkov body associated to the flag E∙:={X=Xr⊃Er⊃{q}}, defined by the surface X and the exceptional divisor Er given by any divisorial valuation of the complex projective plane P2, with respect ...

    • openAccess   Seshadri-type constants and Newton-Okounkov bodies for non-positive at infinity valuations of Hirzebruch surfaces 

      Galindo, Carlos; Monserrat, Francisco; Moreno Ávila, Carlos Jesús Taylor and Francis (2023-02-01)
      We consider flags E• = {X ⊃ E ⊃ {q}}, where E is an exceptional divisor defining a non-positive at infinity divisorial valuation νE of a Hirzebruch surface Fδ , q a point in E and X the surface given by νE , and determine ...
