High-entropy winning-shift conjecture

About 13 years old · traced to

Fix a finite alphabet SS. For a subshift X⊂SXX\subset S^\mathbb{X}, let h(X)h(X) denote its topological entropy and let W(X)W(X) denote its winning shift. High-entropy winning-shift conjecture. For every ϵ>0\epsilon>0 there exists δ>0\delta>0 such that, if

h(X)>log⁡2∣S∣−δ,h(X)>\log_2|S|-\delta,

then

h(W(X))>1−ϵ.h(W(X))>1-\epsilon.

This predicts that subshifts with entropy arbitrarily close to the maximum possible entropy have winning shifts with entropy arbitrarily close to 11.
