On the Inverse Limits of T 0

چکیده

We show that if X is a locally compact, paracompact and Hausdorff space, then X can be realised as the subspace of all maximal points of the inverse limit of an inverse system of partial orders with an appropriate topology (equivalently T0-Alexandroff spaces). Then, the space X is homeomorphic to a deformation retract of that limit. Moreover, we extend results obtained by Clader and Thibault and show that if K is a simplicial complex, then its realisation |K| can be obtained as the subspace of all maximals of the limit of an inverse system of T0-Alexandroff spaces such that each of them is weakly homotopy equivalent to |K|. Moreover, if K is locally-finite-dimensional and |K| is considered with the metric topology, then this inverse system can be replaced by an inverse sequence.

Inverse Limits on [0, 1] Using Piecewise Linear Unimodal Bonding Maps

In this paper we investigate inverse limits on [0, 1] using a single bonding map chosen from a two-parameter family of piecewise linear unimodal bonding maps. This investigation focuses on the parameter values at the boundary between an hereditarily decomposable inverse limit and an inverse limit containing an indecomposable continuum.

Concerning Dimension and Tree-likeness of Inverse Limits with Set-valued Functions

From a theorem of Van Nall it is known that inverse limits with sequences of upper semi-continuous set-valued functions with 0-dimensional values have dimension bounded by the dimensions of the factor spaces. Information is also available about the dimension of inverse limits with sequences of upper semi-continuous continuum-valued bonding functions having graphs that are mappings on the factor...

Inverse limits with subsets of [ 0 , 1 ] cross [ 0 , 1 ]

The characterization of chainable continua as inverse limits on [0, 1] has resulted in many papers which have contributed to our knowledge of both inverse limits and chainable continua. Quite simple maps on [0, 1] give rise to quite complicated inverse limits. In this paper we begin an investigation of continua that can be represented by inverse limits of closed subsets of the unit square I = [...

One-dimensional Inverse Limits with Set-valued Functions

In this paper we show that an inverse limit is 1-dimensional whenever the bonding functions are upper semi-continuous from [0, 1] into C([0, 1]) and dim(G(fi ◦ fi+1 ◦ · · · ◦ fj)) = 1 for all integers i and j, 1 ≤ i ≤ j. We apply this result to show that such an inverse limit is treelike and also to show that unions of certain finite collections of interval-valued upper semi-continuous function...

Limits for Counting and Compound Processes

1. Counting Processes and the Inverse Relation A counting process is defined in §2.1 of Ross, right at the beginning. It is a generalization of a renewal (counting) process, which in turn is a generalization of a Poisson (counting) process, typically denoted by {N(t) : t ≥ 0}. For a counting process, there are no specific stochastic (distributional) assumptions. The random variable N(t) counts ...

Implementation of Sinc-Galerkin on Parabolic Inverse problem with unknown boundary ‎condition‎

The determination of an unknown boundary condition, in a nonlinaer inverse diffusion problem is considered. For solving these ill-posed inverse problems, Galerkin method based on Sinc basis functions for space and time will be used. To solve the system of linear equation, a noise is imposed and Tikhonove regularization is applied. By using a sensor located at a point in the domain of $x$, say $...
