Global bifurcation result for the p-biharmonic operator
Electronic Journal of Differential Equations, 2001 We prove that the nonlinear eigenvalue problem for the p-biharmonic operator with $p > 1$, and $Omega$ a bounded domain in $mathbb{R}^N$ with smooth boundary, has principal positive eigenvalue $lambda_1$ which is simple and isolated.

An Arnoldi Method for Nonlinear Eigenvalue Problems [PDF]
BIT Numerical Mathematics, 2004 For the nonlinear eigenvalue problem T(lambda)x = 0 we propose an iterative projection method for computing a few eigenvalues close to a given parameter. The current search space is expanded by a generalization of the shift-and-invert Arnoldi method. The resulting projected eigenproblems of small dimension are solved by inverse iteration. The method is

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Voluntary carbon offsetting programs (VCOPs) are available for airline passengers who want to take action and offset their scope 3 emissions. Yet, their uptake is very limited. In this study, we propose an integrated theoretical model involving the norm activation theory and protection motivation theory to understand airline passengers ...

Electronic Journal of Differential Equations, 2017 We derive a priori bounds for positive supersolutions of $-\Delta_p u = \rho(x) f(u)$, where p >1 and $\Delta_p$ is the p-Laplace operator, in a smooth bounded domain of $\mathbb{R}^N$ with zero Dirichlet boundary conditions. We apply our results to

Nonlinear nonhomogeneous Neumann eigenvalue problems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 Summary: We consider a nonlinear parametric Neumann problem driven by a nonhomogeneous differential operator with a reaction which is \((p-1)\)-superlinear near \(\pm\infty\) and exhibits concave terms near zero. We show that for all small values of the parameter, the problem has at least five solutions, four of constant sign and the fifth nodal.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study examines whether corporate social responsibility (CSR) disclosure in IPO prospectuses functions as a credible sustainability signal and how its credibility influences investor responses in U.S. capital markets. Drawing on a sample of 681 IPOs conducted between 2019 and 2023, we employ textual content analysis to construct a ...

A Novel Text‐Based Framework for Forecasting Carbon Prices
Journal of Forecasting, EarlyView.ABSTRACT This study proposes a text‐based framework for predicting EU carbon prices. Using weekly data from 2020 to 2024, we construct a multivariate dataset combining financial indicators, commodity prices, Google Trends measures, and news‐based sentiment extracted using FinBERT.

The Sector Liquidity Timing Ability of Bond Mutual Funds
International Journal of Finance &Economics, EarlyView.ABSTRACT We investigate whether bond mutual fund managers exhibit market liquidity timing skills in the U.S. corporate bond market. At the portfolio level, we find only weak evidence that bond funds adjust their overall market exposure in anticipation of changes in corporate bond market liquidity.

Three solutions for quasilinear equations in Rn near resonance
Electronic Journal of Differential Equations, 2001 We use minimax methods to prove the existence of at least three solutions for a quasilinear elliptic equation in $mathbb {R}^n$ near resonance.
