A Generalized Variational Principle
Canadian Journal of Mathematics, 2001 We prove a strong variant of the Borwein-Preiss variational principle, and show that on Asplund spaces, Stegall's variational principle follows from it via a generalized Smulyan test. Applications are discussed.

On the Ekeland variational principle [PDF]
Journal of Fixed Point Theory and Applications, 2011 For proper lower semicontinuous functionals bounded from below which do not increase upon polarization, an improved version of Ekeland’s variational principle can be formulated in Banach spaces, which provides almost symmetric ...

The strong Ekeland variational principle
Journal of Mathematical Analysis and Applications, 2006 In this paper, we consider the strong Ekeland variational principle due to Georgiev [P.G. Georgiev, The strong Ekeland variational principle, the strong drop theorem and applications, J. Math. Anal. Appl. 131 (1988) 1–21].

Gyarmati’s Variational Principle of Dissipative Processes
Entropy, 2014 Like in mechanics and electrodynamics, the fundamental laws of the thermodynamics of dissipative processes can be compressed into Gyarmati’s variational principle. This variational principle both in its differential (local) and in integral (global) forms

An Ekeland’s variational principle for set-valued mappings with applications
Journal of Computational and Applied Mathematics, 2009 In this paper, we obtain a general Ekeland’s variational principle for set-valued mappings in complete metric space, which is different from those in [G.Y. Chen, X.X.

$${\mathcal {A}}$$-Variational Principles
Milan Journal of Mathematics, 2023 AbstractThough the $${\mathcal {A}}$$ A -quasiconvexity condition has been fully explored since its introduction, no explicit examples of associated variational principles have been considered except in the classical $${\text {curl}}$$ curl -case. Our aim is to propose such a family of

The uncertainty principle: Variations on a theme [PDF]
Bulletin of the American Mathematical Society, 2021 We show how a number of well-known uncertainty principles for the Fourier transform, such as the Heisenberg uncertainty principle, the Donoho–Stark uncertainty principle, and Meshulam’s nonabelian uncertainty principle, have little to do with the structure of the Fourier transform itself.

Variational Principles of Micromagnetics Revisited [PDF]
SIAM Journal on Mathematical Analysis, 2020 We revisit the basic variational formulation of the minimization problem associated with the micromagnetic energy, with an emphasis on the treatment of the stray field contribution to the energy, which is intrinsically non-local. Under minimal assumptions, we establish three distinct variational principles for the stray field energy: a minimax ...
