设0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)},其中0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x)= 0 1:T θ jx ∈ Qn(x).我们证明了log J n /n → 1和log K n(x)/n → 1 a.e.当n → ∞时,a.e.θ。
Let 0 1: ∥x - T θ j x ∥ = ∥j.θ∥ < ½ n } where ∥t∥ = min n , z ‖t-n‖, and K n (x) = min{j ≥ 1: T θ j x ∈ Q n (x)}. We show that log J n /n → 1 and log K n (x)/n → 1 a.e. as n → ∞ for a.e. θ.
