Relative Broken Family Sensitivity

Let π: (X, T) → (Y, S) be a factor map between two topological dynamical systems, and \(\cal{F}\) $$\mathcal{F}$$ a Furstenberg family of ℤ. We introduce the notion of relative broken \(\cal{F}\) $$\mathcal{F}$$ -sensitivity. Let \(\cal{F}_{s}\) $${\mathcal{F}}_s$$ (resp. \(\cal{F}_{\text{pubd}},\cal{F}_{\text{inf}}\) $${\mathcal{F}}_{\text{pubd}},{\mathcal{F}}_{\text{inf}}$$ ) be the families consisting of all syndetic subsets (resp. positive upper Banach density subsets, infinite subsets). We show that for a factor map π: (X, T) → (Y, S) between transitive systems, π is relatively broken \(\cal{F}\) $$\mathcal{F}$$ -sensitive for \(\cal{F}=\cal{F}_{s}\) $$\mathcal{F}={\mathcal{F}}_s$$ or \(\cal{F}_{\text{pubd}}\) $${\mathcal{F}}_{\text{pubd}}$$ if and only if there exists a relative sensitive pair which is an \(\cal{F}\) $$\mathcal{F}$$ -recurrent point of (R_π, T⁽²⁾); is relatively broken \(\cal{F}_{\text{inf}}\) $${\mathcal{F}}_{\text{inf}}$$ -sensitive if and only if there exists a relative sensitive pair which is not asymptotic. For a factor map π: (X, T) → (Y, S) between minimal systems, we get the structure of relative broken \(\cal{F}\) $$\mathcal{F}$$ -sensitivity by the factor map to its maximal equicontinuous factor.
