Zero-Point Problem in Fixed-Point Gauge of Nonperturbative QCD

Modern Physics Letters A, 1997
We discuss the essence of the zero-point in fixed-point gauge of nonperturbative QCD and describe how to set the zero-point appropriately in deriving the nonperturbative quark–gluon three-point vertex functions including gluon condensates.

Interval methods for fixed-point problems

Numerical Functional Analysis and Optimization, 1987
Interval analysis is applied to the fixed-point problem x=ϕ(x) for continuous ϕ:S→S, where the space S is constructed from Cartesian products of the set R of real numbers, with componentwise definitions of arithmetic operations, ordering, and the product topology. With the aid of an interval inclusion φ:IS → IS in the interval space IS corresponding to

Fixed point problems: an introduction

Eletrónica e Telecomunicações, 1996
This paper surveys a number of fundamental results on the existence and uniqueness of fixed points for certain classes of possibly nonlinear operators. I do not try to be exhaustive, but merely to present the results that are more useful in the context of signal and image reconstruction.

Complete problems for fixed-point logics

Journal of Symbolic Logic, 1995
The notion of logical reducibilities is derived from the idea of interpretations between theories. It was used by Lovász and Gács [LG77] and Immerman [Imm87] to give complete problems for certain complexity classes and hence establish new connections between logical definability and computational complexity.However, the notion is also interesting in a ...

General Inequalities and Fixed-Point Problems

1980
The aim of the present paper is to give some general results on fixed-point problems in the setting of an abstract set equipped only with a rather simple mathematical structure.
