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…

A family of special cubic fourfolds with motive of abelian type
Hanine Awada, Michele Bolognesi, Claudio Pedrini
In this short note, we show that there exist one dimensional families of cubic fourfolds with Chow motive of abelian type and finite dimensional inside every Hassett divisor of spe…
