| contents | In this article, we study affine interval exchange transformations (AIETs) which are semi-conjugated to interval exchange transformations (IETs) of hyperbolic periodic type. More precisely, we study the Hausdorff dimension of their invariant measures, as well as the Hausdorff dimension of conformal measures of self-similar interval exchange transformations, and implicit relations between them. Among the highlights of this paper, we provide a precise formula for the Hausdorff dimension when the vector of the logarithm of slopes is of central-stable type with respect to the renormalization matrix. This dimension turns out to be strictly between $0$ and $1$. Moreover, we study the regularity of the semi-conjugacy between an AIET and an IET in the periodic case, deriving explicit formulas for their supremal Hölder exponents. |
