On embedding of linear hypersurfaces
Parnashree Ghosh, Neena Gupta, Ananya Pal
Linear hypersurfaces over a field have been playing a central role in the study of some of the challenging problems on affine spaces. Breakthroughs on such problems have occurr…
A new family of counterexamples to the Zariski Cancellation Problem in positive characteristic
Parnashree Ghosh, Ananya Pal
In this paper, over a field of positive characteristic we exhibit an infinite family of counter examples to the Zariski Cancellation Problem in higher dimensions () wh…
On the family of affine threefolds
Parnashree Ghosh, Neena Gupta, Ananya Pal
In recent decades, linear affine threefolds have enabled researchers to solve some of the challenging problems on affine spaces. Koras-Russell threefolds, especially the Russell Cu…
On characterization of Double Danielewski type algebras
Parnashree Ghosh, Dibyendu Mondal
Let be a field. In this paper, we consider Double Danielewski type algebras over an affine factorial -domain . We observe that this family produces a non-cancellative fam…
