Mapping Chainable Continua onto Dendroids
نویسنده
چکیده
We prove that every chainable continuum can be mapped into a dendroid such that all point-inverses consist of at most three points. In particular, it follows that there exists a finite-to-one map from a hereditarily indecomposable continuum (the pseudoarc) onto hereditarily decomposable continuum. This answers a question by J. Krasinkiewicz.

The Pseudo-circle Is Not Homogeneous
In the first two volumes of Fundamenta Mathematica, Knaster and Kuratowski raised the following two questions [15], [16]: (1) If a nondegenerate, bounded plane continuum is homogeneous, is it necessarily a simple closed curve? (2) Does there exist a continuum each subcontinuum of which is indecomposable? Although Knaster settled the second question in 1922 [14], it was to remain until 1948 for ...
متن کاملAn Arc as the Inverse Limit of a Single Nowhere Strictly Monotone Bonding Map on [0, 1]
Introduction. It is well known that a nondegenerate continuum (compact, connected metric space) is chainable if and only if it is homeomorphic to the limit of an inverse sequence of arcs with bonding maps onto. Several authors have studied chainable continua as inverse limits of arcs and in particular Henderson [3] and Mahavier [4] have contributed to the problem of characterizing the class C o...
متن کاملThe nonexistence of expansive homeomorphisms of chainable continua
A homeomorphism f : X → X of a compactum X with metric d is expansive if there is c > 0 such that if x, y ∈ X and x 6= y, then there is an integer n ∈ Z such that d(f(x), f(y)) > c. In this paper, we prove that if a homeomorphism f : X → X of a continuum X can be lifted to an onto map h : P → P of the pseudoarc P , then f is not expansive. As a corollary, we prove that there are no expansive ho...

This paper is concerned with conditions under which a metric continuum (a compact connected metric space) contains a nondegenerate chainable continuum. This paper is concerned with conditions under which a metric continuum (a compact connected metric space) contains a non-degenerate chainable continuum. By R.H. Bing’s theorem eleven [2] if a metric continuum X contains a non-degenerate subconti...
متن کاملTopology Proceedings 42 (2013) pp. 327-340: Concerning Chainability of Inverse Limits on $[0,1]$ with Set-Valued Functions
Suppose that X1, X2, X3, . . . is a sequence of continua and fi : Xi+1 → 2Xi is an upper semi-continuous set-valued function for each positive integer i; let Gn = {x ∈ ∏n+1 i=1 Xi | xi ∈ fi(xi+1) for 1 ≤ i ≤ n}. We show that if Gn is a chainable continuum for each n ∈ N, then the inverse limit lim ←− is chainable. We use this to show that two well-studied examples of inverse limits on [0, 1] wi...
