We explore various notions of stability for surfaces embedded and immersed in spacetimes initial data sets. The interest such lies their potential to go beyond the variational techniques which often underlie study minimal CMC surfaces. prove two versions Christodoulou–Yau estimate $${\mathbf {H}}$$ -stable surfaces, a Cohn-Vossen type inequality non-compact stable marginally outer trapped surfa...

We demonstrate that the one-dimensional helical Majorana edges of two-dimensional time-reversal symmetric topological superconductors (class DIII) can become gapless and insulating by a combination random edge velocity interaction. Such breaks symmetry inhomogeneously, local broken regions be regarded as static mass potentials or dynamical Ising spins. In both limits, we find such glassy are ge...

Identification of suitable areas for yam production is critical ensuring yield in Nigeria. The study aimed at determining lands Climate, soil, and environmental parameters that have a high contribution to were used developing suitability map using the Analytical Hierarchy Process (AHP). AHP was deriving weights through pairwise comparison technique. According findings, highly (HS), (S), margina...

Abstract The assessment of land suitability is the key to sustained agricultural output. Thus, study aimed assess for irrigation development in West Shewa zone, Oromia, Ethiopia. A GIS-based analytical hierarchy process was applied evaluate a multi-criteria analysis. factors such as soil (depth, drainage, texture, pH, organic carbon, available water content, and salinity), slope, use/cover, pro...
