A general framework for relative equilibria in the symmetric full gravitational N-Body problem - Celestial Mechanics and Dynamical Astronomy
We present a method to determine admissible configurations that lead to relative equilibria in the full gravitational N-body problem. The method exploits the $$\text {SO}(3)$$ SO ( 3 ) symmetry by wor...

⭐️What happens to resonant periodic orbits when you perturb a high-dimensional system? Our new paper answers that by extending the subharmonic Melnikov! We're already preparing a sequel to explore its direct applications to Perturbed Keplerian Systems🚀 onlinelibrary.wiley.com/doi/10.1002/...

An Extension of the Subharmonic Melnikov Method for Resonant Periodic Orbits
We extend the subharmonic Melnikov method to study the persistence of resonant periodic orbits in nonlinear 2n-dimensional systems formed by an integrable zero-order part plus a generic perturbation.....

Our #InternationalDayOfMathematics public lecture 'A world from a sheet of paper' was given by Tadashi Tokieda 📜🗺️ Curious about origami, miura-ori, and how geometry can confer properties such as elasticity? 🧬 Catch up here👉 mathematical-research-institute.sydney.edu.au/a-world-from... #MathSky 🧮

✨Highly recommend Geordie Williamson's brilliant talk. We were lucky to meet Geordie in Sydney in 2022 at @sydmathinst.bsky.social , he lives by his own words: "Mathematics is humanity's longest conversation."✨ youtu.be/0Tgftb5ELvE?... via @YouTube

🔝SymplecticGeometry has its roots in physics. To take a simple example, imagine a pendulum. Don't miss the video of #HolgerDullin and #FranciscoCrespo and how the role of symmetry can change everything! @sydmathinst.bsky.social @sydneymathsstats.bsky.social youtu.be/fdeh3lljA_Q?...
