Abstract

Let T ⁣:[0,1]d[0,1]d T\colon[0,1]^d\to [0,1]^d be a piecewise expanding map with an absolutely continuous invariant measure μ \mu . Let {Hn} \{H_n\} be a sequence of hyperrectangles or hyperboloids centered at the origin. Denote by R({Hn}) \mathcal R(\{H_n\}) the set of points x \mathbf x such that Tnxx+Hn T^n\mathbf x\in \mathbf x+H_n for infinitely many nN n\in\mathbb N , where x+Hn \mathbf x+H_n is the translation of Hn H_n . We prove that if μ \mu is exponential mixing and the density of μ \mu is sufficiently regular, then the μ\mu-measure of R({Hn}) \mathcal R(\{H_n\}) is zero or full according to the sum of the volumes of Hn H_n converges or not. In the case that T T is a matrix transformation, our results extend a previous work of Kirsebom, Kunde, and Persson [to appear in Ann. Sc. Norm. Super. Pisa Cl. Sci., 2023] in two aspects: by allowing the matrix to be non-integer and by allowing the `target' sets Hn H_n to be hyperrectangles or hyperboloids. We also obtain a dimension result when T T is a diagonal matrix transformation.
