Opis

This volume is dedicated to Professor Arto Salomaa on the occasion of his 60th birthday. The 32 invited papers contained in the volume were presented at the festive colloquium, organized by Hermann Maurer at Graz, Austria, in June 1994; the contributing authors are well-known scientists with special relations to Professor Salomaa as friends, Ph.D. students, or co-authors. The volume reflects the broad spectrum of Professor Salomaa's research interests in theoretical computer science and mathematics with contributions particularly to automata theory, formal language theory, mathematical logic, computability, and cryptography. The appendix presents Professor Salomaa's curriculum vitae and lists the more than 300 papers and 9 books he published.

O autorze

Hermann Maurer studierte Mathematik und Physik in Österreich, Informatik in Kanada. Er war einige Jahre in der Industrie tätig, aber ist nun seit mehr als 30 Jahren Universitätsprofessor für Informatik an Universitäten in Kanada, USA, Deutschland, Brasilien, Australien, Neuseeland und vor allem an der Technischen Universität Graz in Österreich. Er ist mit zahlreichen wissenschaftlichen Büchern und über 500 wissenschaftlichen Publikationen in seinem Bereich der Informatik aktiv tätig, ist aber auch seit vielen Jahren schriftstellerisch aktiv, oft unter einem Pseudonym.
