Femininity Repackaged: Postfeminism and ined in a finite dimensional invariant manifold M. When this is the case one obtains the sought finite dimensional dynamical system simply by restricting T(t) to M. In general this construction is only formal because M cannot be computed explicitly and therefore the dynamical system describing the f

,Functional Differential Equations and Jensen’s Inequality,te the Banach space of continuous functions ψ: [−h, 0] →R. with the norm., where |•| is any convenient norm in R.. For H>0, let C. designate the open ball in C for which ||ψ||<H. It is assumed that F:[0,∞) x C.→R. is continuous and takes bounded sets into bounded sets.

Method of Upper and Lower Solutions for Nonlinear Integral Equations and an Application to an Infecriable t. Equation (1) can be interpreted as a model for the spread of some infectious diseases with periodic contact rate (see Cooke and Kaplan ). In this case, x(t) means the proportion of infectives in the population at time t; f(t,x(t)) means the proportion of new infectives per unit time (f(

Perturbed Dual Semigroups and Delay Equations,heory of ordinary and partial differential equations. This statement is equally valid for retarded functional differential equations, but here the variation — of — constants formula shows a peculiar feature. Indeed, in the book of . we find that the formula involves the so-called fundamental mat

Longtime Behavior for a Class of Abstract Integrodifferential Equations,i-group {T(t)|t ≥ 0} acting on a Banach space .. We further stipulate that O ∈ .(A). For α∈(0, 1), A. denotes the fractional power of the operator A and . represents the interpolation space defined by the α power of A, i.e. . with
