Dynamic asymptotic dimension growth for group actions and groupoids
We introduce the notion of dynamic asymptotic dimension growth for actions of discrete groups on compact spaces, and more generally for locally compact étale groupoids. Moreover, we demonstrate that the asymptotic dimension growth for a discrete metric space of bounded geometry i...

Properties and calculation of pythagorean triples
Pythagorean triples, which are sets of three natural numbers (a,b,c) satisfying the equation a2+b2=c2, are among the oldest and most fascinating subjects in number theory. This paper is motivated by the potential of Pythagorean triples as a vehicle for curriculum enrichment at va...

Recent Increaseof Greenhouse Gas Emissions from Cryosphere-InfluencedReservoirs under Climate Change
Abstract Global warming leads to cryosphere degradation, transferring large amounts of terrestrial carbon and nitrogen to reservoirs, which may accelerate the release of greenhouse gases (GHGs) to the atmosphere. However, the spatial dynamics and decadal trends of GHG emissions f...
