• The description of the reachable states of the heat equation is one of the central questions in control theory. The aim of this work is to present new results for the 1-D heat equation with boundary control on the segment [0,π]. In this situation it is known that the reachable states are holomorphic in a square D the diagonal of which is given by [0,π]. The most precise results obtained recently say that the reachable space is contained between two well known spaces of analytic functions: the Smirnov space E2(D) and the Bergman space A2(D). We show that the space of reachable states is exactly the sum of two Bergman spaces on sectors the intersection of which is D. In order to get a more precise information on this sum of Bergman spaces, we also prove that it contains a certain weighted Bergman space on D.
