Given a dynamical system

$(Ω,Σ,μ, τ)$

with

$μ$

a non-atomic probability measure and

$τ$

an invertible measure preserving ergodic transformation, we prove that the maximal operator, considered by I. Assani, Z. Buczolich and R. D. Mauldin in 2005,

${N^*}f\left( x \right) = \mathop {\sup }\limits_{\alpha > 0} \alpha \# \left\{ {k \ge 1:\frac{{\left| {f\left( {{\tau ^k}x} \right)} \right|}}{k} > \alpha } \right\}$

satisfies that

${N^*}:\left[ {L \log_3 L (μ)} \right] \longrightarrow L^{1, ∞}(μ)$

is bounded where the space

$\left[ {L \log_3 L (μ)} \right]$

is defined by the condition

$\Vert f\Vert_{\left[ {L \log_3 L (μ)} \right]} = ∈t_0^1 \frac{\sup\limits_{t≤q y}tf_μ^*(t)}{y} \log_3 \frac 1y dy < ∞,$

with

$\log_3 x = 1+\log_+\log_+\log_+ x$

and

$f^*_μ$

the decreasing rearrangement of

$f$

with respect to

$μ$

. This space is near

$L \log_3 L (μ)$

, which is the optimal Orlicz space on which such boundedness can hold. As a consequence, the space

$\left[ {L \log_3 L (μ)} \right]$

satisfies the Return Times Property for the Tail; that is, for every

$f∈\left[ {L \log_3 L (μ)} \right]$

, there exists a set

$X_0$

so that

$μ(X_0) = 1$

and, for all

$x_0∈ X_0$

, all dynamical systems

$(Y,\mathcal{C},ν, S)$

and all

$g∈ L^1(ν)$

, the sequence

$R_ng(y) = \frac1nf(τ^nx_0)g(S^ny) \overset{n\to∞}\longrightarrow 0,\;\;\;\;\;\; ν\text{-a.e. } y∈ Y.$

Keywords: Return times theorem, Muckenhoupt weights, Yano's extrapolation, Rubio de Francia's extrapolation.
