Constructions and deformations of Calabi--Yau 3-folds in codimension 4

Sumayya Moshin, Shaheen Nazir, Muhammad Imran Qureshi

We construct polarized Calabi--Yau 3-folds with at worst isolated canonical orbifold points in codimension 4 that can be described in terms of the equations of the Segre embedding…

Terminal Fano four folds in low codimension

Muhammad Imran Qureshi

We construct well-formed and quasismooth terminal Fano 4-folds of index 1 in low codimension containing at worst isolated orbifold points. We provide a certain classification of th…

Projection Cascades of models of log del Pezzo surfaces

Muhammad Imran Qureshi

We introduce the notion of type-I projection cascade for a biregular model (infinite series) of log del Pezzo surfaces. We study the existence of type-I projection cascades for kno…

Obrifold del Pezzo surfaces in $P^{1} \times P^{1} \times P^{1}$ format

Muhammad Imran Qureshi

We construct two types of wellformed and quasismooth biregular models (infinite series) of rigid orbifold del Pezzo surfaces having their (sub) anti-canonical embeddings in $\mathb…
