Orbital stability of solitary wave solutions of the derivative nonlinear Schrödinger equation in the endpoint case
Jia Shen, Yifei Wu, Changping Yang
In this paper, we consider the orbital stability of solitary waves for the derivative nonlinear Schrödinger equation $$iq_t+q_{xx}+i\partial_x\bigl(|q|^2q\bigr)=0, \quad (t,x)\in\m…

Phase-Gated Constrained Reinforcement Learning for End-to-End Capture and Detumbling of Non-Cooperative Targets
Álvaro Belmonte-Baeza, Celia Redondo-Verdú, José L. Ramón +3
Active debris removal requires a servicer spacecraft to approach a non-cooperative tumbling object, capture it, and arrest its rotation. This sequence is conventionally divided amo…
