Stacks, Monodromy and Symmetric Cubic Surfaces
We investigate monodromy groups arising in enumerative geometry, with a particular focus on how these groups are influenced by prescribed symmetries. To study these phenomena effectively, we work in the framework of moduli stacks rather than moduli spaces. This perspective proves broadly useful for understanding and constructing monodromy. We illustrate these ideas through several examples, with special attention to the 27 lines on a cubic surface, assuming the surface admits a given symmetry g…

Reliable Image Transmission in CPS-based Pub/Sub
Developments in communication and automation have driven the expansion of distributed networks, essential for IoT and CPS development in industrial applications requiring reliable image processing and real-time adaptability. Although broadly adopted, there is a literature gap regarding the performance of MQTT protocol for image sharing and transmission under high-traffic scenarios with intermittent connectivity, restricting its use in critical IoT and CPS applications. In this context, the pres…

Realistic consecutive galaxy mergers form eccentric PTA sources
Results from pulsar timing arrays (PTAs) show evidence of a gravitational wave background (GWB) consistent with a population of unresolved supermassive black hole binaries (BHBs). The observed spectrum shows a flattening at lower frequencies that can be explained by a population of eccentric BHBs. This study aims to determine the dynamical evolution and merger timescales of the most massive BHBs, which are potential sources of the GWB. We select successive galactic major mergers from the Illust…
