Magnetosphere-Ionosphere-Thermosphere Coupling Study at Jupiter Based on Juno's First 30 Orbits and Modeling Tools. [PDF]

J Geophys Res Space Phys, 2022
Abstract The dynamics of the Jovian magnetosphere is controlled by the interplay of the planet's fast rotation, its solar‐wind interaction and its main plasma source at the Io torus, mediated by coupling processes involving its magnetosphere, ionosphere, and thermosphere.

Optimality Conditions for Group Sparse Constrained Optimization Problems

Mathematics, 2021
In this paper, optimality conditions for the group sparse constrained optimization (GSCO) problems are studied. Firstly, the equivalent characterizations of Bouligand tangent cone, Clarke tangent cone and their corresponding normal cones of the group ...

Strong Invariance Using Control Barrier Functions: A Clarke Tangent Cone Approach [PDF]

2020 59th IEEE Conference on Decision and Control (CDC), 2020
Many control applications require that a system be constrained to a particular set of states, often termed as safe set. A practical and flexible method for rendering safe sets forward-invariant involves computing control input using Control Barrier Functions and Quadratic Programming methods.

A characterization of Clarke’s strict tangent cone via nonlinear semigroups [PDF]

Proceedings of the American Mathematical Society, 1985
Clarke’s strict tangent cone T X ↑ ( a ) T_X^ \uparrow (a) at a ∈ X a \in X to a closed subset of a Banach space E E is shown to contain the limit inferior of tangent cones T

Existence of Equilibria and Fixed Points of Set-Valued Mappings on Epi-Lipschitz Sets with Weak Tangential Conditions

Journal of Function Spaces, 2016
We prove a new result of existence of equilibria for an u.s.c. set-valued mapping F on a compact set S of Rn which is epi-Lipschitz and satisfies a weak tangential condition.

Clarke’s Tangent Cones, Subgradients, Optimality Conditions, and the Lipschitzness at Infinity

SIAM Journal on Optimization
We first study Clarke's tangent cones at infinity to unbounded subsets of $\mathbb{R}^n.$ We prove that these cones are closed convex and show a characterization of their interiors. We then study subgradients at infinity for extended real value functions on $\mathbb{R}^n$ and derive necessary optimality conditions at infinity for optimization problems.
