Applicable Algebra, Error-Correcting Codes, Combinatorics and Computer Algebra 4th International Conference, AAECC-4, Karlsruhe, FRG, September 23-26, 1986. Proceedings

This volume contains the proceedings of the 4th International Conference on Applicable Algebra, Error-Correcting Codes, Combinatorics and Computer Algebra (AAECC-4), held in Karlsruhe, 23-26 September, 1986. Selected papers which were given at the conference have been reviewed a second time and are presented here.
