The image of the Veronese mapping is a determinantal variety; an elementary proof

Rahim Zaare-Nahandi

Let $ν_{d} : P^{n} ⟶ P^{N}$ be the Veronese mapping of degree $d$ where $N = (n n + d) - 1$ . By an elementary approach it is shown that $ν_{d}$ is an i…

On Tusi's Classification of Cubic Equations and its Connections to Cardano's Formula and Khayyam's Geometric Solution

Bahman Kalantari, Rahim Zaare-Nahandi

Omar Khayyam's studies on cubic equations inspired the 12th century Persian mathematician Sharaf al-Din Tusi to investigate the number of positive roots. According to the noted mat…

Simplicial complexes of small codimension

Matteo Varbaro, Rahim Zaare-Nahandi

We show that a Buchsbaum simplicial complex of small codimension must have large depth. More generally, we achieve a similar result for $CM_{t}$ simplicial complexes, a notion…

Cohen-Macaulay lexsegment complexes in arbitrary codimension

Hassan Haghighi, Siamak Yassemi, Rahim Zaare-Nahandi

We characterize pure lexsegment complexes which are Cohen-Macaulay in arbitrary codimension. More precisely, we prove that any lexsegment complex is Cohen-Macaulay if and only if i…

A canonical polytopal resolution for transversal monomial ideals

Rahim Zaare-Nahandi

Let $S = k [x_{11}, \dots, x_{1 b_{1}}, \dots, x_{n 1}, \dots, x_{n b_{n}}]$ be a polynomial ring in $m = b_{1} + \dots + b_{n}$ variables over a field $k$ . For all $j$ , $1 \leq j \leq n$ , le…

What to do to have your paper rejected!

Mohammad Sal Moslehian, Rahim Zaare-Nahandi

We aim to highlight certain points and considerations for graduate students and young researchers, which should be avoided in submissions to good research journals. Observing these…
