Stability estimate for the heat equation backward in time with Neumann and integral boundary conditionsIn this paper, we first prove that the heat equation backward in time with Neumann and integral boundary conditions is an ill-posed problem. Then, we establish a stability estimate of Hölder type for... Author: Duc Duc Van Keyword: The heat equation backward in time stability estimate ill-posed problem.

Ill-posedness and stability es-timate for the heat equation backward in time with Dirichlet and integral boundary condi-tionsIn this paper, we first prove that the heat equation backward in time with Dirichlet and integral boundary conditions is an ill-posed problem. Then, we establish a stability estimate of Hölder type... Author: Duc Duc Van, Linh Phan Hoai Keyword: Heat equation backward stability estimate ill-posed problem.

Risk-sensitive spatio-temporal graph reinforcement learning for predictive and propulsion-aware routing in 6G-enabled FANETsFlying ad hoc networks (FANETs) in 6G environments require routing schemes that can cope with rapid topology changes, limited UAV energy resources, and unstable air-to-air links. This paper proposes a...
