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 ...

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.

On stability and the Łojasiewicz exponent at infinity of coercive polynomials [PDF]
Kybernetika, 2019 The paper deals with coercive polynomials \(f\in\mathbb{R}[X_1,\dots,X_n]\), that is, polynomials having the growth property \(f(x)\to +\infty\) whenever \(\|x\|\to +\infty\). The authors analyze the relationship between the growth and stability properties of coercive polynomials.

The linear and non linear Rayleigh-Taylor instability for the quasi isobaric profile [PDF]
, 2007 We study the stability of the system of the Euler equation in the neighborhood of a stationary profile associated with the quasi isobaric model in a gravity field. This stationary profile is not bounded below, hence the operator is not coercive.

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 ...
