School of History and Philosophy of Science RESEARCH SEMINAR [The University of Sydney] [https://d31hzlhk6di2h5.cloudfront.net/20230911/cb/75/e2/c4/b84bae4efd3f95e0a8dd36fd_360x512.png] The Liar paradox, the halting problem and the edge of chaos Mikhail Prokopenko (USyd)
Dates: Monday, 18/9/2023 Time: 5:30pm Venue: Madsen Building (F09), Level 3, Room 331 How to register: Free, no registration required Abstract: We will explore several fundamental relations between formal systems, algorithms, and dynamical systems, focussing on the roles of self-reference and computational undecidability. This comparative analysis will emphasise three factors: (i) the program-data duality; (ii) the potential to access an infinite computational medium; and (iii) the ability to implement negation. Importantly, the program-data duality requires that a computational agent must be able to store and process encoded information, as well as create self-referential meta-level simulations. Finally, within Gödel – Turing – Post framework, we will argue that undecidability leads to novelty generation, via the emergence of functional self-descriptions across major transitions: genetic, linguistic and cultural. Bio: Prof. Mikhail Prokopenko leads the Centre for Complex Systems at the University of Sydney. He holds PhD in Computer Science, MA in Economics, and MSc in Applied Mathematics. Mikhail has a strong international reputation in modelling and simulation of complex self-organising systems, with over 200 publications and h-index of 43. His cross-disciplinary research in information theory, critical phenomena and artificial intelligence has been applied to pandemic and crisis modelling, systems biology, urban dynamics, and other diverse areas.
