On the diagonal of low bidegree hypersurfaces
Morten Lüders, Elia Fiammengo
We study the existence of a decomposition of the diagonal for bidegree hypersurfaces in a product of projective spaces. Using a cycle theoretic degeneration technique due to Lange,…

On the diagonal of quartic hypersurfaces and -complete intersection -folds
Elia Fiammengo, Morten Lüders
We study the question of the existence of a decomposition of the diagonal for very general quartic and -complete intersection -folds. Using cycle-theoretic techniques of…
