Abundance of 3-Planes on Real Projective Hypersurfaces
[OWP-2014-14] Finashin, Sergey; Kharlamov, Viatcheslav (Mathematisches Forschungsinstitut Oberwolfach, 2014-11-11)We show that a generic real projective n-dimensional hypersurface of odd degree d, such that 4(n−2)=(d+33), contains "many" real 3-planes, namely, in the logarithmic scale their number has the same rate of ... -
Chirality of Real Non-Singular Cubic Fourfolds and Their Pure Deformation Classification
[OWP-2019-14] Finashin, Sergey; Kharlamov, Viatcheslav (Mathematisches Forschungsinstitut Oberwolfach, 2019-05-15)In our previous works we have classified real non-singular cubic hypersurfaces in the 5-dimensional projective space up to equivalence that includes both real projective transformations and continuous variations of ... -
Deformation Classification of Real Non-Singular Cubic Threefolds with a Marked Line
[OWP-2018-02] Finashin, Sergey; Kharlamov, Viatcheslav (Mathematisches Forschungsinstitut Oberwolfach, 2018-02-21)We prove that the space of pairs (X,l) formed by a real non-singular cubic hypersurface X⊂P4 with a real line l⊂X has 18 connected components and give for them several quite explicit interpretations. ...
