Half-homogeneous indecomposable circle-like continuum

A continuum is said to be $frac12$-homogeneous if there are exactly two types of points. We give an example of a $frac12$-homogeneous indecomposable circle-like continuum. This answers a question of V. Neumann-Lara, P. Pell...

On indecomposability in chaotic attractors

We exhibit a Li-Yorke chaotic interval map F such that the corresponding inverse limit does not contain an indecomposable subcontinuum. Our result contrasts spacecontains an indecomposable subcontinuum. From a result of Barge and Ma...

Planar embeddings of chainable continua

We prove that for a chainable continuum where every point has only finitely many coordinate projections contained in a zigzag there exists a planar embedding such that this point is accessible. This partially answers a question of Nadler and...

1/kappa-Homogeneous long solenoids

-like indecomposable continuum. We also show that for each uncountable cardinal continuum, and let p =?p1,p2,??p?=?p1,p2,?? be a sequence of positive integers. We that for every cardinal ??1, there is an ordered continu...

Universal quadratic forms and indecomposables over biquadratic fields

The aim of this article is to study (additively) indecomposable algebraic integers OK of biquadratic number fields K and universal totally positive quadratic forms with coefficients in OK. There are given sufficient conditions for an ind...

Trace and norm of indecomposable integers in cubic orders

We study the structure of additively indecomposable integers in families of totally real cubic fields. We prove that for cubic orders in these fields, the minimal traces of indecomposable integers multiplied by totally positive elem...

Continuous curves of nonmetric pseudo-arcs and semi-conjugacies to interval maps

In 1985 M. Smith constructed a nonmetric pseudo-arc; i.e. a Hausdorff homogeneous, hereditary equivalent and hereditary indecomposable continuum. Taking advantage of a decomposition theorem of W. Lewis, he obtained it as a long inve...

Minimal rank of universal lattices and number of indecomposable elements in real multiquadratic fields

of indecomposable elements modulo totally positive units, obtaining density zero statements. We also study the structure of indecomposable elements in real biquadratic fields, and compute a system of indecomposable element...

Universal quadratic forms and indecomposables over biquadratic fields

The aim of this article is to study (additively) indecomposable algebraic integers $mathcal O_K$ of biquadratic number fields $K$ and universal totally positive quadratic forms with coefficients in $mathcal O_K$. There are given sufficient c...
