SUMMARY

For my Ph. D., I am developing a common language for concurrency and planning
that aims at bringing these two fields closer. Such a language will allow to transfer
mathematical notions from concurrency to planning, and provide a platform for a
structural analysis of plans. For this purpose, I am using the logical systems of the
recently developed proof theoretical formalism, the calculus of structures.

This formalism admits deductive systems which extend different fragments of linear
logic with a self-dual, non-commutative logical operator. By resorting to these
systems, which can not be designed in any standard sequent calculus, parallel and
sequential composition of the developed language can be naturally expressed by
means of commutative and non-commutative logical operators. While inference
rules of the proof theoretical systems provide an operational semantics of the
language I develop, a behavioral semantics is obtained by borrowing methods
from concurrency theory.

I am also implementing the proof search in these logical systems. These
implementations do not only provide the tools for the language developed, but
also assist the proof theoretical research on different logics, i.e., classical logic,
modal logics, linear logic, within this formalism. In order to reduce
nondeterminism in proof search, I develop new proof theoretical techniques.
Besides making the above mentioned implementations more efficient, these
techniques are used as combinatorial proof theoretic tools while proving
properties of these logical systems.
