On quartic double fivefolds and the matrix factorizations of exceptional quaternionic representations
Roland Abuaf
We study quartic double fivefolds from the perspective of Fano manifolds of Calabi-Yau type and that of exceptional quaternionic representations. We first prove that the generic qu…

Scheme-theoretic Whitney conditions and applications to tangency of projective varieties
Roland Abuaf
We investigate a scheme-theoretic variant of Whitney condition a. If X is a projec-tive variety over the field of complex numbers and Y X a subvariety, then X satisfies g…
