In this work we study the Hausdorff dimension and limit capacity for repellers of certain non-uniformly expanding maps f defined on a subset of a manifold. This subset is covered by a finite number of compact domains with pairwise disjoint interiors (the complement of the union of these domains is called hole) each of which is mapped smoothly to the union of some of the domains with a subset of the hole. The maps are not assumed to be hyperbolic nor conformal. We provide conditions to ensure that the limit capacity of the repeller is less than the dimension of the ambient manifold. We also prove continuity of these fractal invariants when the volume of the hole tends to zero.

    The n-dimensional compact topological space is called to be a Cantor Manifold (CM), if it is not a sum of two proper closed subsets with (n-2)-dimensional intersection. It is by definition a Strongly Cantor Manifold (SCM), if it is not a countable sum of proper closed subsets with no more than...

    The notion of compatible apparition points is introduced for non-Hausdorff manifolds, and properties of these points are studied. It is well known that the Hausdorff property is independent of the other conditions given in the standard definition of a topological manifold. In much of literature,...

    For a sequence of functions on the unit disk D ⊂ ℂ, the map of the boundary circle to a space of compact sets with Hausdorff metric which takes each point e ∈ ∂ D to the limit set of the sequence of functions at this point is considered. It is shown that such a map is of...

    In the 20th century, physicists have understood space and time as being coupled into a space-time manifold, a fundamental arena in which everything takes place. Space-time was considered to have three spatial dimensions and one temporal dimension. Out of the experimental facts, one can conclude...

    Existence of equilibrium of a continuous preference relation p or correspondence P on a compact topological space W can be proved either by assuming acyclicity or convexity (no point belongs to the convex hull of its preferred set). Since both properties may well be violated in both political...

    We work in set theory without the axiom of choice: ZF. We show that the axiom BC: Compact Hausdorff spaces are Baire, is equivalent to the following axiom: Every tree has a subtree whose levels are finite, which was introduced by Blass (cf. [4]). This settles a question raised by Brunner (cf....
