Classification of low degree del Pezzo orbifolds II
Saptarshi Dandapat
Del Pezzo orbifolds are del Pezzo surfaces equipped with a strict normal crossing divisor, called boundary, such that the log anticanonical divisor is ample. We classify del Pezzo…

Campana Rational Connectedness and Weak Approximation of Del Pezzo Orbifolds
Saptarshi Dandapat
We prove that a del Pezzo orbifold of degree less than 7, and del Pezzo orbifolds of higher degree with irreducible boundary are strongly Campana uniruled, and deduce that it is Ca…

Classification of low degree del Pezzo orbifolds
Saptarshi Dandapat
In this paper we classify low degree del Pezzo orbifolds with irreducible boundaries. In order to achieve desired boundaries, we classify low degree curves on low degree del Pezzo…
