On rigidity of Pham-Brieskorn surfaces

Neena Gupta, Ananya Pal

It is well known that, over an algebraically closed field $k$ of characteristic zero, for any three integers $a, b, c \geq 2$ , any Pham-Brieskorn surface $B_{(a,b,c)}:= k[X,Y,Z]/(X^a…

Retracts of Laurent polynomial rings

Neena Gupta, Takanori Nagamine

Let $R$ be an integral domain and $B = R [x_{1}, \dots, x_{n}]$ be the polynomial ring. In this paper, we consider retracts of $B [1/ M]$ for a monomial $M$ . We show that (1) if $M=\prod_{i=…
