Beyond Frames: Semi-frames and Reproducing Pairs,s a partial inner product space (.-space) with an .. central Hilbert space. A first possibility is to work in a rigged Hilbert space. Then, after describing the general construction, we will discuss two characteristic examples, namely, we take for the partial inner product space a Hilbert scale or a
