Maximum principle for a nonlinear size-structured model of fish and fry management [PDF]
Nonlinear Analysis, 2018 This paper investigates the maximum principle for a nonlinear size-structured model that describes the optimal management of the fish resources taking into account harvesting the fish and putting the fry.

Graphical Ekeland’s principle for equilibrium problems [PDF]
Proceedings of the American Mathematical Society, Series B, 2022 In this paper, we give a graphical version of the Ekeland’s variational principle (EVP) for equilibrium problems on weighted graphs. This version generalizes and includes other equilibrium types of EVP such as optimization, saddle point, fixed point and variational inequality ones. We also weaken the conditions on the class of bifunctions for which the

A New Equilibrium Version of Ekeland’s Variational Principle and Its Applications
Axioms, 2022 In this note, a new equilibrium version of Ekeland’s variational principle is presented. It is a modification and promotion of previous results. Subsequently, the principle is applied to discuss the equilibrium points for binary functions and the fixed ...

Equivalents of Ekeland's principle [PDF]
Bulletin of the Australian Mathematical Society, 1993 In this note we present a new result which is equivalent to the celebrated Ekeland's variational principle, and a set of implications which includes a new non-convex minimisation principle due to Takahashi.

Ekeland’s variational principle for interval-valued functions
Computational and Applied Mathematics, 2023 In this paper, we attempt to propose Ekeland's variational principle for interval-valued functions (IVFs). To develop the variational principle, we study the concept of sequence of intervals. In the sequel, the idea of gH-semicontinuity for IVFs is explored.

Researching what we practice—The paradigm of systemic family research: Part 1
Family Process, Volume 62, Issue 3, Page 947-960, September 2023., 2023 Abstract This is part 1 of two articles that focus on the ideological and philosophical preference regarding how to relate to and conduct research in the field of systemic couple and family therapy. Thus, this article outlines the theoretical groundwork for part 2 of “Researching what we practice” in the same journal.

Equilibria of time‐inconsistent stopping for one‐dimensional diffusion processes
Mathematical Finance, Volume 33, Issue 3, Page 797-841, July 2023., 2023 Abstract We consider three equilibrium concepts proposed in the literature for time‐inconsistent stopping problems, including mild equilibria (introduced in Huang and Nguyen‐Huu (2018)), weak equilibria (introduced in Christensen and Lindensjö (2018)), and strong equilibria (introduced in Bayraktar et al. (2021)). The discount function is assumed to be

Existence results for a sublinear second order Dirichlet boundary value problem on the half-line [PDF]
Opuscula Mathematica, 2020 In this paper we study the existence of nontrivial solutions for a boundary value problem on the half-line, where the nonlinear term is sublinear, by using Ekeland's variational principle and critical point theory.
