asymptotic equivalence for some functional equation of Volterra type.
Closed form solutions of iterative functional differential equations.
Constructive solution of coupled second order delay differential equations with variable coefficients.
Continuous transformations of differential equations with delays.
Coordinate description of analytic relations
In this paper we present an algebraic approach that describes the structure of analytic objects in a unified manner in the case when their transformations satisfy certain conditions of categorical character. We demonstrate this approach on examples of functional, differential, and functional differential equations.
