Shape dynamics of bouncing droplets

DV Svintradze - Scientific reports, 2019 - nature.com
Oscillating shape motion of a freely falling and bouncing water droplet has long fascinated
and inspired scientists. We propose dynamic non-linear equations for closed, two …

Generalization of the Kelvin equation for arbitrarily curved surfaces

DV Svintradze - Physics Letters A, 2020 - Elsevier
Capillary condensation, which takes place in confined geometries, is the first-order vapor-to-
liquid phase transition and is explained by the Kelvin equation, but the equation's …

Moving Manifolds and General Relativity

DV Svintradze - arXiv preprint arXiv:2406.08382, 2024 - arxiv.org
We revise general relativity (GR) from the perspective of calculus for moving surfaces (CMS).
While GR is intrinsically constructed in pseudo-Riemannian geometry, a complete …
