Trees as data and file structures,ystematized the accumulated knowledge about data structures in his 1968 book on Fundamental Algorithms, he devoted half the space to tree structures. During the seventies, data structures based on trees were extended to files on secondary storage and to multidimensional problems such as multi-key ac

Infinitary relations,on of concurrent processes, we shall use mainly infinitary rational relations. A forthcomming paper of the same author is devoted to theim definition and properties. The author has had very helpful discussions with A. Arnold, L. Boasson, F. Boussinot, G. Roncairol and G. Ruggin.

: Application to the programming of Algebraic Abstract Data Types in PROLOG,g in PROLOG respectively..An AAT is considered as an interpretor, the semantical actions of which are rewrite rules..The power of the methodology makes it possible to construct one and many-sorted types, and may be used as an aid for proofs of properties..This approach leads to a clean, rapid, and a

Easy solutions are hard to find,olution in a non-trivial "contraction algebra" in which one of the components is a projection. This problem, which arose in where all solutions of a system of recursion equations in a contraction algebra A were found, is related to the equivalence problem for deterministic pushdown automata..Sec

,Calcul du rang des ∑-arbres infinis regulers,. The complexity of scalar iterative expressions can be defined in various way and so it is for regular ∑-trees. Here, we present a method for calculating the "rank" of such a tree, with and without concatenation..In the flow chart case, our algorithm allows to decide if a chart G is (syntactically)

Grammars without erasing rules. the OI case,ing rules : incomplete rules, ε-rules and monadic ε-rules (i.e. rules like X(x.)→x.). For grammars with erasing rules of just the third class, erasing-free grammars can be obtained and a construction is provided. Other results are negative and we prove that generally erasing rules cannot be avoided.

Amotz Bar-Noy,Keerti Choudhary,David Peleg,Dror Rawitzrmal atmosphere, the enthusiasm of the participants and the intensity of the scientific interaction have all conspired to make these meetings wonderful learning experiences. The XIIth Workshop (held from July 1 - 7, 1993) was once again a topical meeting within the general area of Differential Geome
