Following the existence of generalized exponential dichotomies and corresponding invariant manifolds for functional differential equations, the homoclinic solution of a delay equation studied by Lin (1986, J. Differential Equations 63, 227 254) proved to be reducible to a finite dimensional one.

โฆ Synopsis
A sufficient and necessary condition for a planar critical point to be isolated as an invariant set is given. Using the concept of an isolated invariant set, some existence criteria of orbits connecting two critical points bifurcating from a single critical point for planar differential equations depending on a parameter are given.

The paper studies differential equations of the form u (x) = f (x, u(x), ฮป(x)), u(x0 ) = u0 , where the righthand side is merely measurable in x. In particular sufficient conditions for the continuous and the differentiable dependence of solution u on the data and on the parameter ฮป are stated.
The work deals with the eigenvalue problem of ordinary dierential equations with non-linear dependence of the equation coecients on the parameter. A set of theorems for the eigenvalue estimators is presented, on the basis of which a new algorithm can be proposed for determining the ยฎrst eigenvalue o
In 1981, L. A. Rubel found an explicit algebraic differential equation (ADE) of order four such that every real continuous function on the real line can be uniformly approximated by the C โ -solutions of this ADE. It is shown that an ADE of order five exists, where the C โ -solutions additionally sa
