In this paper we study the space $\mathbb{L}(n)$ of $n$-gons in the plane degenerated to segments. We prove that this space is a smooth real submanifold of $\mathbb{C}^n$, and describe its topology in terms of the manifold $\mathbb{M}(n)$ of $n$-gons

To gain insight into the dynamics of the CN + C2H6 gas-phase reaction, quasi-classical trajectory (QCT) calculations were performed on a full-dimensional analytical potential energy surface. This reaction presents very high exothermicity, -22.20 kcal

Quasi-classical trajectory (QCT) calculations were conducted on the newly developed full-dimensional potential energy surface, PES-2023, to analyse two critical aspects: the influence of vibrational versus translational energy in promoting reactivity

Temperature dependence of the thermal rate constants and kinetic isotope effects (KIE) of the CN + C2H6 gas-phase hydrogen abstraction reaction was theoretically determined within the 25-1000 K temperature range, i.e., from ultra-low to high-temperat

We provide two new exact Sidon-Ramsey numbers to the list known so far. We also improve the upper bounds of the next two Sidon-Ramsey numbers. In doing so, we comment on the tendencies we found on the Sidon-Ramsey partitions that were studied to obta

For a given positive integer $k$, the Sidon-Ramsey number $\SR(k)$ is defined as the minimum value of $n$ such that, in every partition of the set $[1, n]$ into $k$ parts, there exists a part that contains two distinct pairs of numbers with the same

Populations have changed their habits and consumption as a result of COVID-19. In the case of Mexico City, this situation has possibly led households to purchase more products such as bottled water and to consume the same amount or less tap water. Th

Abstract Background Hedera helix L. is an invasive weed species introduced in several regions of the world, so it is relevant to study its effects on the plant community and the changes occurring after its eradication. We established invaded (with/wi
