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 ... -
Newton–Okounkov Bodies of Exceptional Curve Plane Valuations Non-positive at Infinity
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. -
Newton–Okounkov bodies of exceptional curve valuations
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 ... -
Seshadri-type constants and Newton-Okounkov bodies for non-positive at infinity valuations of Hirzebruch surfaces
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 ...
