Generalized Fefferman-Graham gauge and boundary Weyl structures
Published 2025-02-01“…To address these, we introduce a new codimension-two counterterm, or corner term, that ensures the finiteness of the gravitational action. From here, we construct the quantum-generating functional, the holographic stress tensor, and compute the corresponding Weyl anomaly, showing that the latter is now expressed in a full Weyl covariant way. …”

Conic-Based 3D Rockfall Modeling with QGIS-Qproto Software: A Case Study of Mazı Village, Nevşehir (Ürgüp)
Published 2023-07-01“…Based on these results, the maximum values of the rockfall model within the study area were generally reached in areas with high slope values, and it was observed that the energies and velocities of rock blocks attenuated at points with decreased slope, indicating the influence of the existing gravitational condition. Rockfall susceptibility degrees were categorized into five classes, and it was observed that the trajectories of fallen blocks, resulting from rockfalls, corresponded mainly to the moderate-high and high susceptibility classes, where they were scattered and dispersed. …”
