More on the pressing down game
We investigate the pressing down game and its relation to the Banach Mazur game. In particular we show: Consistently relative to a supercompact, there is a nowhere precipitous normal ideal I on א2 such that player nonempty wins the pressing down game of length א1 on I even if player empty starts. For the proof, we construct a forcing notion to force the following: There is normal, nowhere preci...
متن کاملWinning the pressing down game but not Banach-Mazur
Let S be the set of those α ∈ ω2 that have cofinality ω1. It is consistent relative to a measurable that the nonempty player wins the pressing down game of length ω1, but not the Banach Mazur game of length ω+1 (both games starting with S).
متن کاملProving the Pressing Game Conjecture on Linear Graphs
The pressing game on black-and-white graphs is the following: Given a graph G(V,E) with its vertices colored with black and white, any black vertex v can be pressed, which has the following effect: (a) all neighbors of v change color, i.e. white neighbors become black and vice versa, (b) all pairs of neighbors of v change connectivity, i.e. connected pairs become unconnected, unconnected ones b...
متن کاملThe Effectiveness of Game Therapy on Social Skills, Anxiety, and Aggression in Down syndrome Children
The aim of this study was to evaluate the effectiveness of therapeutic games on social skills, anxiety and aggression in children with Down syndrome. This is a quasi-experimental study with pre-test and post-test design with control group. The statistical population of the study included all children with Down syndrome under the protection of Kermanshah Welfare Organization in 2018. A total of ...
متن کاملMore on the Cut and Choose Game
We improve on the results of [Vel] and give some examples. In [Jech], a number of infinite games on (complete) Boolean algebras were defined. Among them was the following Prikry-style “cut and choose” game Gc&c : I p, b0 b1 . . . . . . . . . bi . . . . . . . . . . i < ω II r0 r1 . . . . . . . . . ri . . . . . . . . . . where p, bi’s are elements of the Boolean algebra B in question and ri ∈ 2 f...
