Motivated by the study of the propagation of electromagnetic waves through a multi-layered optical medium, we prove the existence of two different kinds of homoclinic solutions to the origin in a Schrödinger equation with a nonlinear term. We use a Krasnoselskii fixed point theorem together with a compactness criterion due to Zima. The main results are illustrated with concrete examples of prac...

Motivated by the conjecture that the cosmological constant problem is solved by strong quantum effects in the infrared we use the exact flow equation of Quantum Einstein Gravity to determine the renormalization group behavior of a class of nonlocal effective actions. They consist of the Einstein-Hilbert term and a general nonlinear function Fk(V ) of the Euclidean spacetime volume V . For the V...

The purpose of this study is to integrate the findings of the studies related to the relationship between CEO compensation and firm performance in Asian countries. The second concern of the paper is to explore the moderating role of country-specific characteristics on the pay-performance relationship in Asian markets. In order to achieve the study’s objective, meta-analysis technique is utilize...

This paper is an attempt to analyze the impact of income taxes and market capitalization on fixed investment (investment in tangible assets) by manufacturing companies listed on KSE. This paper basically examines that how corporate income taxes affect fixed investment by reducing cash flow available for a firm to invest and how the firm size in the lights of market capitalization affects fixed ...
