Springer Monographs in MathematicsA space is a non-empty set (no matter how the nature of its elements). Thus, the concept of a space is the most general in mathematics. Instead of the term ., it is possible to use another synonyms as follows: . etc. In a space we may introduce the concept of an operator.

Well-Posedness in a Riesz Basis Setting,The theory of asymptotic spaces is used for formal solution of an operator equation of the form . = .(.). Formal solution is the first (and may be very difficult) step of the total asymptotic solution of the equation. Since many different spaces are used for different problems, we consider this notion in an axiomatic form.

Well-Posedness in a Riesz Basis Setting,Power functions play an important role in the mathematical analysis. We (naturally and usefully) extend the set of all power functions preserving its some ‘good’ asymptotic properties in a neighborhood of the infinitely large point.

Problems with Weakened Gap Conditions,In this chapter we consider functions of the power order of growth in a central sector . or in a sufficiently small sector .. on the complex plane.

Springer Monographs in MathematicsHere we consider a so called (scalar) . of . which is a system of the form . where .. (.) and ..(.) are complex-valued functions defined on an interval ]a, b[ of the real axis (one or both of the points . and . can be infinitely large, ., . = 1, 2,..., .). System (8.1) is equivalent to a single matrix equation of the form

Multidimensional Ingham-Type Theorems,In this chapter we consider a single linear differential equation of .th order of the form . in a central sector . of the complex plane for sufficiently large argument . where ..(.),..., .. (.) are holomorphic functions.
