Derivations of plane algebroid curves

Sagnik Chakraborty, R. V. Gurjar, Madhuparna Pal

In this paper, we study the derivations of an irreducible plane algebroid curve $R := \frac{k [[ X , Y ]]}{( f )}$ , which is not regular. Since the normalization of $R$ is isomorphic to $k[…

Monomial and binomial retracts of polynomial rings

Sagnik Chakraborty, Madhuparna Pal

Let $R$ be a ring and $B := R [X_{1}, \dots, X_{n}]$ the polynomial ring in $n$ variables over $R$ . In this article, we consider retractions $φ : B ⟶ B$ such that $φ (X_{i})$ …
