Full Description
The Third Kurt G|del Symposium, KGC'93, held in Brno, Czech
Republic, August1993, is the third in a series of biennial
symposia on logic, theoretical computer science, and
philosophy of mathematics. The aim of this meeting wasto
bring together researchers working in the fields of
computational logic and proof theory. While proof theory
traditionally is a discipline of mathematical logic, the
central activity in computational logic can be foundin
computer science. In both disciplines methods were invented
which arecrucial to one another. This volume contains the
proceedings of the symposium. It contains contributions by
36 authors from 10 different countries. In addition to 10
invited papers there are 26 contributed papers selected from
over 50 submissions.
