Multiple solutions for a singular quasilinear elliptic system. [PDF]
ScientificWorldJournal, 2013 We consider the multiplicity of nontrivial solutions of the following quasilinear elliptic system , , , , , where , , , , , . The functions , , , , , , and satisfy some suitable conditions. We will prove that the problem has at least two nontrivial

Maximum principle for a stochastic delayed system involving terminal state constraints. [PDF]
J Inequal Appl, 2017 We investigate a stochastic optimal control problem where the controlled system is depicted as a stochastic differential delayed equation; however, at the terminal time, the state is constrained in a convex set.

A generalization of Ekeland's variational principle by using the τ-distance with its applications. [PDF]
J Inequal Appl, 2017 In this paper, a new version of Ekeland’s variational principle by using the concept of τ-distance is proved and, by applying it, an approximate minimization theorem is stated.

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 ...

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.

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

Equilibrium investment with random risk aversion
Mathematical Finance, Volume 33, Issue 3, Page 946-975, July 2023., 2023 Abstract We solve the problem of an investor who maximizes utility but faces random preferences. We propose a problem formulation based on expected certainty equivalents. We tackle the time‐consistency issues arising from that formulation by applying the equilibrium theory approach.

Campbell Systematic Reviews, Volume 19, Issue 2, June 2023., 2023 Abstract This is the protocol for a Campbell systematic review. The main objective of this review is to answer the research question: What are the effects of organised sport on risk behaviour, personal, emotional and social skills of young people, who either have experienced or is at‐risk of experiencing an adverse outcome?
