A note on a continuation principle for compact perturbations of the identity
Differential and Integral Equations, 1992 This article deals with the equation \(F(x,\lambda)=0\) where \(F(x,\lambda)=x-k(x,\lambda)\), \((x,\lambda)\in {\mathcal O}\subseteq X\times\mathbb{R}^ n\), \(X\) is a real Banach space, \(k(x,\lambda)\) is continuous on \({\mathcal O}\) and compact on the open sets \({\mathcal O}(\varepsilon)\), \(\bigcup_ \varepsilon {\mathcal O}(\varepsilon ...

The Fréchet Derivative of an Analytic Function of a Bounded Operator with Some Applications
International Journal of Mathematics and Mathematical Sciences, 2009 The main result in this paper is the determination of the Fréchet derivative of an analytic function of a bounded operator, tangentially to the space of all bounded operators. Some applied problems from statistics and numerical analysis are included as a

Electronic Journal of Differential Equations, 2018 This article concerns the stability of traveling wavefronts for a three-component Lotka-Volterra competition system on a lattice. By means of the weighted energy method and the comparison principle, it is proved that the traveling wavefronts with ...

Local infrared safety in time-ordered perturbation theory
Journal of High Energy PhysicsWe develop a general expression for weighted cross sections in leptonic annihilation to hadrons based on time-ordered perturbation theory (TOPT). The analytic behavior of the resulting integrals over spatial momenta can be analyzed in the language of ...

The perturbation effect in wildlife systems: an emergent property of simple models [PDF]
, 2012 Population reduction is often used as a control strategy when managing infectious diseases in wildlife populations, however it disrupts existing social structures and increases movement of infectives due to the vacuum effect, which may lead to enhanced ...
