1.	Eriksson, T., et al. (author) Successive Encoding of Correlated Sources 1982 Reports (other academic/artistic)abstract The encoding of a discrete memoryless multiple source for reconstruction of a sequence with is considered. We require that the encoding should be such that is encoded first without any consideration of , while in a seeond part of the encoding this latter sequence is encoded based on knowledge of the outcome of the first encoding. The resulting scheme is called successive encoding. We find general outer and inner bounds for the corresponding set of achievable rates along with a complete single letter characterization for the special case . Comparisons with the Slepian-Wolf problem [3] and the Ahlswede-Körner-Wyner side information problem [2 ], [9) are carried out.

Considering a symmetric set of quadrature points on the unit circle, error estimates are derived for the scalar flux in $L_P $ norms for $1 \leqq p \leqq \infty $. A postprocessing procedure giving improved $L_\infty $ estimates is also analyzed. Finally error estimates are given for simple isolated eigenvalues of the solution operator.
