ASPECTS OF COMPUTATION AND AUTOMATA THEORY WITH APPLICATIONS [EPUB ebook] 

This volume results from two programs that took place at the Institute for Mathematical Sciences at the National University of Singapore: Aspects of Computation — in Celebration of the Research Work of Professor Rod Downey (21 August to 15 September 2017) and Automata Theory and Applications: Games, Learning and Structures (20–24 September 2021).

The first program was dedicated to the research work of Rodney G. Downey, in celebration of his 60th birthday. The second program covered automata theory whereby researchers investigate the other end of computation, namely the computation with finite automata, and the intermediate level of languages in the Chomsky hierarchy (like context-free and context-sensitive languages).

This volume contains 17 contributions reflecting the current state-of-art in the fields of the two programs.

Readership: Advanced undergraduate students, graduate students and researchers interested in automata theory, computabillty theory, complexity theory and recursion theory.

Key Features:

• Comprehensive and original collection of cutting-edge topics on automata theory, computational complexity and recursion theory


• The contributors are expert researchers in these fields and both contribute new scientific results and ideas for future directions


• The articles are an interdisciplinary mix dealing with computations from the concrete level of the theory of finite automata through the theoretical limits explored in recursion theory and also cover the middle in between with excursions into game theory and parameterized complexity
