Oka and Alexander polynomials of symplectic curves and divisibility relations
Hanine Awada, Marco Golla
We prove Libgober's divisibility relations for Oka and Alexander polynomials of symplectic curves in the complex projective plane. Along the way, we give new proofs of the divisibi…

K3 surfaces and cubic fourfolds with Abelian motive
Hanine Awada, Michele Bolognesi, Robert Laterveer +1
We show that cubic fourfolds with lattice of algebraic 2-cycles of rank greater than 19 have abelian and finite dimensional (in the sense of Kimura) Chow motive. This also implies…

Moduli of Cubic fourfolds and reducible OADP surfaces
Michele Bolognesi, Zakaria Brahimi, Hanine Awada
In this paper we explore the intersection of the Hassett divisor , parametrizing smooth cubic fourfolds containing a plane with other divisors .…
