  • Hyperkähler manifolds of curves in twistor spaces? 
    Bielawski, Roger (Kiev : NAS Institute of Mathematics, 2014)
    We discuss hypercomplex and hyperkähler structures obtained from higher degree curves in complex spaces fibring over P1.
  • Intersecting quantum gravity with noncommutative geometry - A review? 
    Aastrup, Johannes; Grimstrup, Jesper Moller (Kyiv : Institute of Mathematics of National Academy of Sciences of Ukraine, Department of Applied Research, 2012)
    We review applications of noncommutative geometry in canonical quantum gravity. First, we show that the framework of loop quantum gravity includes natural noncommutative structures which have, hitherto, not been explored. ...
  • The Mori fan of the Dolgachev–Nikulin–Voisin family in genus 2 
    Hulek, Klaus; Liese, Carsten ([Erscheinungsort nicht ermittelbar] : [Verlag nicht ermittelbar], 2022)
    In this paper we study the Mori fan of the Dolgachev–Nikulin–Voisin family in degree 2 as well as the associated secondary fan. The main result is an enumeration of all maximal dimensional cones of the two fans. © by the ...
  • N=4 multi-particle mechanics, WDVV equation and roots 
    Lechtenfeld, Olaf; Schwerdtfeger, Konrad; Thürigen, Johannes (Kiew : National Academy of Science of Ukraine, 2011)
    We review the relation of N=4 superconformal multi-particle models on the real line to the WDVV equation and an associated linear equation for two prepotentials, F and U. The superspace treatment gives another variant of ...
  • The noncommutative ward metric 
    Lechtenfeld, Olaf; Maceda, Marco (Kyiv : Institute of Mathematics of National Academy of Sciences of Ukraine, Department of Applied Research, 2010)
    We analyze the moduli-space metric in the static non-Abelian charge-two sector of the Moyal-deformed CP1 sigma model in 1 + 2 dimensions. After carefully reviewing the commutative results of Ward and Ruback, the noncommutative ...
  • On the automorphisms of a rank one Deligne-Hitchin moduli space 
    Biswas, Indranil; Heller, Sebastian (Kiev : Institute of Mathematics of National Academy of Sciences of Ukraine, 2017)
    Let X be a compact connected Riemann surface of genus g ≥ 2, and let MDHbe the rank one Deligne-Hitchin moduli space associated to X. It is known that MDHis the twistor space for the hyper-Kähler structure on the moduli ...
  • On the motive of O'Grady's six-dimensional hyper-Kähler varieties 
    Floccari, Salvatore ([Erscheinungsort nicht ermittelbar] : [Verlag nicht ermittelbar], 2023)
    We prove that the rational Chow motive of a six-dimensional hyper-Kähler variety obtained as symplectic resolution of O'Grady type of a singular moduli space of semistable sheaves on an Abelian surface A belongs to the ...
  • Q`-cohomology projective planes and Enriques surfaces in characteristic two 
    Schütt, Matthias (s.l. : Association de l'Épijournal de Geometrie Algebrique, 2019)
    We classify singular Enriques surfaces in characteristic two supporting a rank nine configuration of smooth rational curves. They come in one-dimensional families defined over the prime field, paralleling the situation in ...
  • Restriction of odd degree characters of Sn 
    Bessenrodt, Christine; Giannelli, Eugenio; Olsson, Jorn B. (Kiev : Institute of Mathematics of National Academy of Sciences of Ukraine, 2017)
    Let n and k be natural numbers such that 2k < n. We study the restriction to Sn−2k of odd-degree irreducible characters of the symmetric group Sn. This analysis completes the study begun in [Ayyer A., Prasad A., Spallone ...
  • Smoothing cones over K3 surfaces 
    Coughlan, Stephen; Sano, Taro (France : Association Epiga, 2018)
    We prove that the affine cone over a general primitively polarised K3 surface of genus g is smoothable if and only if g ≤ 10 or g = 12. We also give several examples of singularities with special behaviour, such as ...
