Abstract : The problem of determining the initial data of a secondorder parabolic partialdifferential equation defined on a bounded spatial domain from an observation of the solution at a given time T > O is considered. The observation is in the form of a weighted spatial average of the solution at time T. Two sufficient conditions for the solvability of this problem are given. The first condition pertains to the form of the integral kernel involved in the observation and the second pertains to the smoothness of the initial data. The case where the observation is expressed in terms of a reproducing kernel of a Hilbert space is treated for the heat equation defined on a onedimensional bounded spatial domain. (Author)
