In 1988, for the 1st time, the 2 overseas meetings AAECC-6 and ISSAC'88 (International Symposium on Symbolic and Algebraic Computation, see Lecture Notes in machine technology 358) have taken position as a Joint convention in Rome, July 4-8, 1988. the subjects of the 2 meetings are actually extensively regarding one another and the Joint convention offered a great party for the 2 learn groups to satisfy and proportion medical stories and effects. The court cases of the AAECC-6 are integrated during this quantity. the most themes are: utilized Algebra, concept and alertness of Error-Correcting Codes, Cryptography, Complexity, Algebra dependent equipment and purposes in Symbolic Computing and machine Algebra, and Algebraic equipment and functions for complicated details Processing. Twelve invited papers on topics of universal curiosity for the 2 meetings are divided among this quantity and the succeeding Lecture Notes quantity dedicated to ISSACC'88. The lawsuits of the fifth convention are released as Vol. 356 of the Lecture Notes in machine Science.
