K3 carpets on minimal rational surfaces and their smoothings
Purnaprajna Bangere, Jayan Mukherjee, Debaditya Raychaudhury
In this article, we study K3 double structures on minimal rational surfaces . The results show there are infinitely many non-split abstract K3 double structures on $Y = \mathbb{…

Remarks on projective normality for certain Calabi-Yau and hyperkähler varieties
Jayan Mukherjee, Debaditya Raychaudhury
We prove some results on effective very ampleness and projective normality for some varieties with trivial canonical bundle. In the first part we prove an effective projective norm…

On The Projective Normality And Normal Presentation On Higher Dimensional Varieties With Nef Canonical Bundle
Jayan Mukherjee, Debaditya Raychaudhury
In this article we prove new results on projective normality and normal presentation of adjunction bundle associated to an ample and globally generated line bundle on higher dimens…
