Ordinal Neural Collapse as a Representation Prior for Visual Navigation
E-In Son, Jung-Taak Kim, Seung-Woo Seo
Learning robust navigation policies directly from visual observations remains a fundamental challenge in vision-based robotic navigation. In end-to-end imitation learning approache…

Limits on the mass of compact objects in HoÅava-Lifshitz gravity
Edwin J. Son
It is known that there exist theoretical limits on the mass of compact objects in general relativity. One is the Buchdahl limit for an object with an arbitrary equation-of-state th…

Vanishing Compactness Gap and Fermionic Compact Dark Matter in HoÅava-Lifshitz Gravity
Edwin J. Son, Kyungmin Kim, John J. Oh
We show that the gap in the compactness between black holes and neutron stars witnessed in general relativity may be vanishing in HoÅava-Lifshitz (HL) gravity. Assuming a fermion…
