   • 2015, Alexey Korepanov, “Linear response for intermittent maps with summable and nonsummable decay of correlations”, in arXiv‎^[1]:

     We show that despite the absence of a spectral gap for all $\alpha \in (0,1)$ and despite nonsummable correlations for $\alpha \ge 1/2$, the map $\alpha \mapsto \int \phi d{\nu }_{\alpha }$ is continuously differentiable for $\phi \in L^q[0,1]$ for $q$ sufficiently large..
