Stability for the spherically symmetric Einstein–Vlasov system–a coercivity estimate [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 2013 AbstractThe stability of static solutions of the spherically symmetric, asymptotically flat Einstein–Vlasov system is studied using a Hamiltonian approach based on energy-Casimir functionals. The main results are a coercivity estimate for the quadratic part of the expansion of the natural energy-Casimir functional about an isotropic steady state, and ...

Weighted K–stability and coercivity with applications to extremal Kähler and Sasaki metrics
Geometry & Topology, 2023 We show that a compact weighted extremal Kahler manifold (as defined by the third named author) has coercive weighted Mabuchi energy with respect to a maximal complex torus in the reduced group of complex automorphisms. This provides a vast extension and a unification of a number of results concerning Kahler metrics satisfying special curvature ...

A note on well-posedness of source identification elliptic problem in a Banach space
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 We study the source identification problem for an elliptic differential equation in a Banach space. The exact estimates for the solution of source identification problem in H¨older norms are obtained. In applications, four elliptic source identification

Harris’s Coercive Discourse Is Stabilizing: Discourse Strategies and Effects [PDF]
Advances in Sciences and Humanities, 2021 Since politicians make use of language in their quest to garner support and credibility, among other things, many coercive strategies are utilized by recourse to some manipulative avenues. These same coercive strategies happen in the matrix of a peculiar socio-cultural environment independently from ideologies and common or shared goals.

Remarks on Input-to-State Stability and Non-Coercive Lyapunov Functions [PDF]
2018 IEEE Conference on Decision and Control (CDC), 2018 We consider an abstract class of infinite-dimensional dynamical systems with inputs. For this class the significance of noncoercive Lyapunov functions is analyzed. It is shown that the existence of such Lyapunov functions implies integral input-to-integral state stability. Assuming further regularity it is possible to conclude input-to-state stability.

Coercivity and stability results for an extended Navier-Stokes system [PDF]
Journal of Mathematical Physics, 2012 In this paper, we study a system of equations that is known to extend Navier-Stokes dynamics in a well-posed manner to velocity fields that are not necessarily divergence-free. Our aim is to contribute to an understanding of the role of divergence and pressure in developing energy estimates capable of both controlling the nonlinear terms, and being ...
