Meager-nowhere Dense Games (iii): Remainder Strategies
نویسنده
چکیده
Player ONE chooses a meager set and player TWO, a nowhere dense set per inning. They play ω many innings. ONE's consecutive choices must form a (weakly) increasing sequence. TWO wins if the union of the chosen nowhere dense sets covers the union of the chosen meager sets. A strategy of TWO which depends on knowing only the uncovered part of the most recently chosen meager set is said to be a remainder strategy. TWO has a winning remainder strategy for this game played on the real line with its usual topology.

Cardinal invariants for C-cross topologies
C-cross topologies are introduced. Modifications of the Kuratowski-Ulam Theorem are considered. Cardinal invariants add , cof, cov and non with respect to meager or nowhere dense subsets are compared. Remarks on invariants cof(nwdY ) are mentioned for dense subspaces Y ⊆ X.
متن کاملBanach-Mazur Games on Graphs
We survey determinacy, definability, and complexity issues of Banach-Mazur games on finite and infinite graphs. Infinite games where two players take turns to move a token through a directed graph, thus tracing out an infinite path, have numerous applications in different branches of mathematics and computer science. In the usual format, the possible moves of the players are given by the edges ...
متن کاملA big symmetric planar set with small category projections
We show that under appropriate set theoretic assumptions (which follow from Martin’s axiom and the continuum hypothesis) there exists a nowhere meager set A ⊂ R such that (i) for each continuous nowhere constant function f : R → R the set {c ∈ R : π[(f + c) ∩ (A×A)] is not meager} is meager, and (ii) the set {c ∈ R : (f + c) ∩ (A × A) = ∅} is nowhere meager for each continuous function f : R → ...
متن کاملRohlin Properties for Z Actions on the Cantor Set
We study the space H(d) of continuous Z-actions on the Cantor set, particularly questions on the existence and nature of actions whose isomorphism class is dense (Rohlin’s property). Kechris and Rosendal showed that for d = 1 there is an action on the Cantor set whose isomorphism class is residual; we prove in contrast that for d ≥ 2 every isomorphism class in H(d) is meager. On the other hand,...
متن کاملBaire Category and Nowhere Differentiability for Feasible Real Functions
A notion of resource-bounded Baire category is developed for the class PC[0,1] of all polynomial-time computable real-valued functions on the unit interval. The meager subsets of PC[0,1] are characterized in terms of resource-bounded Banach-Mazur games. This characterization is used to prove that, in the sense of Baire category, almost every function in PC[0,1] is nowhere differentiable. This i...
