Jackknifing fixed points of iterations

Biometrika, 1987
The jackknife method for estimating the dispersion of a statistic T, considered as an estimator of a p-dimensional vector of parameters, can be modified so as to become computationally feasible for the class of statistics that are obtained as limits of iterative processes. Examples are given to show how the method can be applied to the EM algorithm and

Random Relaxation of Fixed-Point Iteration

SIAM Journal on Scientific Computing, 1996
This paper considers a stochastic fixed-point iteration where each coordinate is updated with a certain probability and otherwise left unchanged. The iteration is interesting from the viewpoint of parallel distributed computation because the realized sequences belong to the class of asynchronous fixed-point iterations.

Convergence of the fixed‐point iteration for multilinear PageRank

Numerical Linear Algebra with Applications, 2021
AbstractFixed‐point iteration is a popular method for the multilinear PageRank problem. In [B. Meini, F. Poloni, Perron‐based algorithms for the multilinear PageRank, Numer. Linear Algebra Appl., 25: e2177, 2018], a theorem was proved to determine the behavior of the fixed‐point iteration as the parameter .

Fixed Point Iteration in Availability Modeling

1991
This paper presents a fixed point iteration technique for modeling system availability of large fault tolerant systems. The systems modeled are composed of several subsystems having redundant components. Real systems have a large number of subsystems and very general types of interaction between components within a subsystem and between subsystems ...

Iterative construction of fixed points

Numerical Functional Analysis and Optimization, 1996
Abstract, It is proved that an Ishikawa—type iteration scheme converges to the fixed point of a generalized contraction map in a convex metric space. The class of generalized contraction maps includes all quasi—contraction maps.

Sequential iteration of the Erlang fixed-point equations

Information Processing Letters, 2002
The link or route blocking probabilities of a loss network are typically used to assess its performance. Unfortunately, closed form expressions for these, whilst being easy to write down, are quite intractable to evaluate computationally. Consequently, a number of approximations to the blocking probabilities have been proposed.

Fixed Point Iterations and Global Stability in Economics

Mathematics of Operations Research, 1985
Stability is studied from the point of view of ordinary Picard iteration in a metric space. The Convergence Theorem proved here states that a sequence of Picard iterates converges if the mapping in question is a proper convex combination of a contraction (nonexpansive mapping) and the identity.

Iteration Near a Fixed Point

Journal of Applied Probability, 1975
An exposition is given of the properties of the iterates of complex functions near a fixed point, with explicit expressions for their power series in certain cases. The relevance to problems in genetics and statistics is pointed out.

Fixed point theorems for mappings with lipschitzian iterates

Nonlinear Analysis: Theory, Methods & Applications, 1992
The authors show new fixed point theorems for mappings with Lipschitzian iterates. Let \(C\) be a nonempty subset of a Banach space \(E\). A mapping \(T: C\to C\) is said to be uniformly Lipschitzian if \[ \| T^ n x- T^ n y\|\leq K\| x-y\|, \quad x,y\in C, \quad n=1,2,\ldots\;. \] holds for some \(K>0\).
