In shape theory, the role of the homotopy groups \( \pi_n \) is played by the so-called fundamental groups \( \underline{\pi}{}_n \), introduced by K. Borsuk, and the homology groups which are useful there, are of the Vietoris–Čech type. The classical Hurewicz isomorphism theorem gives a connection between the homotopy groups \( \pi_n \) and the singular homology groups \( H_n \) with integral coefficients. An example of a compactum \( X \) is constructed, showing that there is no exact analogue of the Hurewicz theorem in shape theory. The example is simple: \( X \) is the double suspension of the 3-adic solenoid. The compactum \( X \) is arcwise connected and it has the following properties:

\( \underline{\pi}{}_q(X) \approx 0 \), for \( q=1 \), 2, 3, and
\( \underline{\pi}{}_4(X) \) and \( \check{H}_4(X) \) are not isomorphic.

In this paper, we show that if \( \epsilon > 0 \), then there exists a \( C^{\infty} \) transformation \( G \) from \( R^3 \) into \( R^3 \) such that the unique solution \( \Phi \) to the differential equation \( y^{\prime} = G(y) \) is a dynamical system (a continuous transformation from \( R\times R^3 \) into \( R^3 \) such that \begin{align*} & \Phi(0,p) = p,\\ & \Phi(t_1,\Phi(t_2,p)) = \Phi(t_1+t_2,p), \text{ and}\\ & \tfrac{\partial}{\partial t}\Phi(0,p) = G(p) \end{align*} with the following two properties:

for each point \( p \) in \( R^3 \) and each number \( t \), \( \Phi(t,p) \) is in the \( \epsilon \)-neighborhood for \( p \); and
for each integer \( n\neq 0 \), \( \Phi(n,p) \neq p \).

Notice that the Scottish Book problem number 110 of Ulam follows a corollary where \( f(p) = \Phi(1,p) \) and the manifold is \( R^3 \).

K. Kuperberg: “Homogeneity and twisted products,” Topology Proc. 13 : 2 (1988), pp. 237–248. MR 1053699 Zbl 0714.54005 article

A topological space \( X \) is said to be homogeneous if for every two points \( p \) and \( q \) in \( X \) there exists a homeomorphism \( \phi: X\to X \) such that \( \phi(p) = q \). A Cartesian product of homogeneous spaces is homogeneous. However, if at least one of the Cartesian factors is homeomorphic to the Menger curve \( M \), then the Cartesian product does not have some of the stronger homogeneity-type properties, see [Kennedy Phelps 1980], [Kuperberg et al. 1980] and [Patkowska 1984]. Even more interesting are continua which are not Cartesian products but whose every point has a neighborhood homeomorphic to a Cartesian product with one or more factors homeomorphic to \( M \), see [Kuperberg 1990].

In this paper, twisted products are obtained by making certain identifications on \( M\times M \), \( M\times I \), or \( M\times S^1 \). The construction yields continua whose every point has a homogeneous neighborhood but the space might not be homogenous, see [Kuperberg 1980]. It is shown here that twisted products of two Menger curves are not (with one obvious exception) homeomorphic to the Cartesian product \( M\times M \), but many twisted products of \( M \) and \( I \) are homeomorphic to \( M\times S^1 \).

The homology separation axiom is introduced to investigate homogeneity properties of Cartesian products of continua. We prove that under certain conditions of a homological nature the products are factorwise rigid. Also, if the product \( X\times Y \) of an \( n \)-dimensional representable continuum \( X \) and a non-degenerate continuum \( Y \) is 2-homogeneous, then \( X \) is locally \( n \)-acyclic. In particular, the product \( B\times Y \) of a \( \mu^n \)-manifold \( B \) (based on the \( n \)-dimensional Menger universal compactum \( \mu^n \)) with any non-degenerate continuum \( Y \) is not 2-homogeneous. These theorems generalize a previous result of the same authors and some results of J. Kennedy Phelps.

Using the theory of plugs and the self-insertion construction due to the second author, we prove that a foliation of any codimension of any manifold can be modified in a real analytic or piecewise-linear fashion so that all minimal sets have codimension 1. In particular, the 3-sphere \( S^3 \) has a real analytic dynamical system such that all limit sets are 2-dimensional. We also prove that a 1-dimensional foliation of a manifold of dimension at least 3 can be modified in a piecewise-linear fashion so that so that there are no closed leaves but all minimal sets are 1-dimensional. These theorems provide new counterexamples to the Seifert conjecture, which asserts that every dynamical system on \( S^3 \) with no singular points has a periodic trajectory.

This paper generalizes a theorem of Barge and Gillette asserting that if an orientation preserving plane homeomorphism \( F \) has a fixed prime end associated with an invariant continuum \( \Delta \) which separates the plane into exactly two domains, then \( F \) has a fixed point in \( \Delta \). The generalization goes in two directions. The Barge–Gillette theorem is proved for a continuum with more than two complementary domains if for all but one complementary domains \( U \), \( F \) has a fixed prime end in \( U \). The other generalization addresses the existence of periodic points with least period \( q \) provided certain conditions concerning \( F^q \) and periodic prime ends with the same least period are met.

This paper gives a partial confirmation of a conjecture of Agarwal, Har-Peled, Sharir, and Varadarajan that the total curvature of a shortest path on the boundary of a convex polyhedron in \( \mathbb{R}^3 \) cannot be arbitrarily large. It is shown here that the conjecture holds for a class of polytopes for which the ratio of the radii of the circumscribed and inscribed ball is bounded. On the other hand, an example is constructed to show that the total curvature of a shortest path on the boundary of a convex polyhedron in \( \mathbb{R}^3 \) can exceed \( 2\pi \). Another example shows that the spiralling number of a shortest path on the boundary of a convex polyhedron can be arbitrarily large.

Edited by N. M. Stavrakas and K. R. Allen. Academic Press, New York. MR 383398 Zbl 0323.55021 incollection

In the realm of Borsuk’s theory of shape, where fundamental sequences play the role of mappings (see [Borsuk 1968] for definitions), we prove two isomorphism theorems of the Vietoris-type: one for Borsuk’s fundamental groups and one for Vietoris homology groups. In order to forumlate such theorems in shape theory, one has to introduce first the notion of a fundamental sequence onto (corresponding to a mapping onto) and a condition corresponding to Vietoris’ assumption on the acyclicity of the inverse images of points. Considering the special case of fundamental sequences generated by mappings, we get in Section 2 the following theorem: If \( f \) is a mapping of a pointed compactum \( (X,x_0) \) onto a pointed compactum \( (Y,y_0) \) such that \( f^{-1}(y) \) is approximately \( q \)-connected for each \( q = 0 \), 1, \( \dots, n \) and for each \( y\in Y \), then \( f \) induces an isomorphism between the \( n \)-th fundamental groups \( \underline{\pi}{}_n(X,x_0) \) and \( \underline{\pi}{}_n(Y,y_0) \). As a similar corollary for homology, we get the classical Vietoris isomorphism theorem (see [Begle 1950] and [Vietoris 1927]). A partial generalization of Smale’s Vietoris theorem for homotopy (see [Smale 1957]) is given in Section 3 as a further application of our theorem for Borsuk’s fundamental groups.
