Fractal and Fractional, 2022 This paper addresses some existence, attractivity and controllability results for semilinear integrodifferential equations having non-instantaneous impulsions on an infinite interval via resolvent operators in case of neutral and state-dependent delay ...

Attractive and non-attractive currencies [PDF]
Journal of International Money and Finance, 2021 In the foreign exchange market, time-varying transaction costs and interest rates may define the time-varying set of attractive currencies for investors. Our study shows that when the currencies are attractive, they tend to deviate from the uncovered interest rate parity and to comove with the global stochastic discount factor (SDF).

Explicit Conditions for Stability of Nonlinear Scalar Delay Impulsive Difference Equation
Advances in Difference Equations, 2010 Sufficient conditions are obtained for the uniform stability and global attractivity of the zero solution of nonlinear scalar delay impulsive difference equation, which extend and improve the known results in the literature. An example is also worked out

Ambivalence et complexité des nuits urbaines contemporaines : le cas de Bordeaux
Bollettino della Società Geografica Italiana, 2019 This article focuses on the night-time in Bordeaux, as a complex and ambivalent space-time. The urban night is a space-time no less complex than the daytime, as we will see with the example of the city of Bordeaux.

Physically attractive faces attract us physically [PDF]
Cognition, 2020 When interacting with other humans, facial expressions provide valuable information for approach or avoid decisions. Here, we consider facial attractiveness as another important dimension upon which approach-avoidance behaviours may be based. In Experiments 1-3, we measured participants' responses to attractive and unattractive women's faces in an ...

Electronic Journal of Qualitative Theory of Differential Equations, 2012 This paper deals with the existence and the attractivity of solutions of a class of fractional order functional Riemann-Liouville Volterra-Stieltjes partial integral equations. Our results are obtained by using Schauder's fixed point theorem.

Journal of Statistical Physics, 2015 We prove that the complex conjugate (c.c.) eigenvalues of a smoothly varying real matrix attract (Eq. 15). We offer a dynamical perspective on the motion and interaction of the eigenvalues in the complex plane, derive their governing equations and discuss applications. C.c. pairs closest to the real axis, or those that are ill-conditioned, attract most
