The Mendez-Pinto-Villarreal Conjecture for some classes of monomial ideals

Paromita Bordoloi, Kanoy Kumar Das, Rajiv Kumar

Characterizing when the symbolic and ordinary powers of an ideal coincide is a central problem in commutative algebra, and ideals satisfying this property are called Simis ideals.…

Simis and packing properties of Alexander dual of connected ideals

Om Prakash Bhardwaj, Kanoy Kumar Das, Rutuja Sawant

In this article, we investigate when the ordinary and symbolic powers of the Alexander dual of connected ideals of graphs coincide, and provide a complete classification of all suc…

Hilbert Coefficients and Regularity of Binomial Edge Ideals

Kanoy Kumar Das, Rajiv Kumar, Paramhans Kushwaha

Let $G$ be a simple graph on $n$ vertices, and let $J_{G}$ denotes the corresponding binomial edge ideal in $S = K [x_{1}, \dots, x_{n}, y_{1}, \dots, y_{n}]$ , where $K$ is a fie…

Admissible set and squarefree-power-like function with applications to squarefree symbolic powers

Trung Chau, Kanoy Kumar Das, Amit Roy +1

We introduce the abstract notion of squarefree-power-like functions, which unify the sequences of squarefree ordinary and symbolic powers of squarefree monomial ideals. By employin…

Trees whose path ideals have linear quotients

Trung Chau, Kanoy Kumar Das, Animikha Dutta Dhar +2

For any integer $n$ , we classify all trees whose $n$ -path ideals have linear quotients.

Admissible matchings and the Castelnuovo-Mumford regularity of square-free powers

Trung Chau, Kanoy Kumar Das, Amit Roy +1

Let $I$ be any square-free monomial ideal, and $H_{I}$ denote the hypergraph associated with $I$ . Refining the concept of $k$ -admissible matching of a graph defined by Erey…

Support-2 monomial ideals that are Simis

Paromita Bordoloi, Kanoy Kumar Das, Rajiv Kumar

A monomial ideal $I \subseteq K [x_{1}, \dots, x_{n}]$ is called a Simis ideal if $I^{(s)} = I^{s}$ for all $s \geq 1$ , where $I^{(s)}$ denotes the $s$ -th symbolic power of $I$ . Let…

Edge ideals with linear quotients and without homological linear quotients

Trung Chau, Kanoy Kumar Das, Aryaman Maithani

A monomial ideal $I$ is said to have homological linear quotients if for each $k \geq 0$ , the homological shift ideal $HS_{k} (I)$ has linear quotients. It is a well-known fac…

Square-free powers of Cohen-Macaulay simplicial forests

Kanoy Kumar Das, Amit Roy, Kamalesh Saha

Let $I (Δ)^{[k]}$ denote the $k^{th}$ square-free power of the facet ideal of a simplicial complex $Δ$ in a polynomial ring $R$ . Square-free powers are intimately related to…

Ordinary and symbolic powers of edge ideals of weighted oriented graphs

Arindam Banerjee, Kanoy Kumar Das, S. Selvaraja

Let $D$ be a weighted oriented graph and $I (D)$ be its edge ideal. In this paper, we show that all the symbolic and ordinary powers of $I (D)$ coincide…
