A symplectic Brezis–Ekeland–Nayroles principle [PDF]
Mathematics and Mechanics of Solids, 2016 We propose a modification of the Hamiltonian formalism which can be used for dissipative systems. This work continues a previous work on Hamiltonian inclusions and advances by the introduction of a symplectic version of the Brezis–Ekeland–Nayroles principle. As an application we show how standard plasticity can be treated in our formalism.

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?

Bundling and nonlinear pricing in telecommunications
The RAND Journal of Economics, Volume 54, Issue 2, Page 268-298, Summer 2023., 2023 Abstract I develop a multiproduct nonlinear pricing model where a firm sells both discrete and continuous services to consumers with multidimensional heterogeneity. I derive the optimal selling mechanism and provide primitive conditions under which different bundling strategies arise. Exploiting both the firm and the consumer's optimality conditions, I

Journal of Applied Mathematics, Volume 2023, Issue 1, 2023., 2023 In this article, we deal with the nonlocal elliptic problems of the Kirchhoff type involving the Hardy potential and critical nonlinearity on a bounded domain in R3. Under an appropriate condition on the nonhomogeneous term and using variational methods, we obtain two distinct solutions.

On Ekeland’s variational principle [PDF]
Journal of Fixed Point Theory and Applications, 2011 For proper lower semi-continuous functionals bounded 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 points.

Critical Fractional p‐Laplacian System with Negative Exponents
Journal of Function Spaces, Volume 2023, Issue 1, 2023., 2023 In this paper, we consider a class of fractional p‐Laplacian problems with critical and negative exponents. By decomposition of the Nehari manifold, the existence and multiplicity of nontrivial solutions for the above problems are established with respect to a sufficiently small parameter.

Journal of Management Studies, Volume 59, Issue 8, Page 2024-2066, December 2022., 2022 Abstract How and when does engagement with a stigmatized organization lead to the transfer of its stigma to organizations and individuals associating with it? To answer this question, we conduct an inductive study of the process of stigma transfer and the conditions determining social actors’ susceptibility to such courtesy stigma. We build our process

On the demand for telemedicine: Evidence from the COVID‐19 pandemic
Health Economics, Volume 31, Issue 7, Page 1491-1505, July 2022., 2022 Abstract Telemedicine can expand access to health care at relatively low cost. Historically, however, demand for telemedicine has remained low. Using administrative records and a difference‐in‐differences methodology, we estimate the change in demand for telemedicine experienced after the onset of the COVID‐19 epidemic and the imposition of mobility ...

Solitary waves in nonlocal NLS with dispersion averaged saturated nonlinearities [PDF]
, 2017 A nonlinear Schr\"odinger equation (NLS) with dispersion averaged nonlinearity of saturated type is considered. Such a nonlocal NLS is of integro-differential type and it arises naturally in modeling fiber-optics communication systems with periodically ...
