Abstract:

We study the logic of dynamical systems, that is, logics and proof principles for properties of dynamical systems. Dynamical systems are mathematical models describing how the state of a system evolves over time. They are important in modeling and understanding many applications, including embedded systems and cyber-physical systems. In discrete dynamical systems, the state evolves in discrete steps, one step at a time, as described by a difference equation or discrete state transition relation. In continuous dynamical systems, the state evolves continuously along a function, typically described by a differential equation. Hybrid dynamical systems or hybrid systems combine both discrete and continuous dynamics. This is a brief survey of differential dynamic logic for specifying and verifying properties of hybrid systems. We explain hybrid system models, differential dynamic logic, its semantics, and its axiomatization for proving logical formulas about hybrid systems. We study differential invariants, i.e., induction principles for differential equations. We briefly survey theoretical results, including soundness and completeness and deductive power. Differential dynamic logic has been implemented in automatic and interactive theorem provers and has been used successfully to verify safety-critical applications in automotive, aviation, railway, robotics, and analogue electrical circuits.

That is really interesting.

Just before I googled it, I tried to summarize my special interests - and it took a few hours, when I gave them the title axiomatization of dynamical systems. (Writing about how I came from my passion for polymath stuff and chaos theory to that would exceed the margin right now.)

Please bare with me, the next stated thoughts might be very ill-formulated gibberish at this stage of thought ...primordial soup or such heeh...

Axiomatization: definition in merriam-webster: the process of reducing down to a system of basic truths or axioms

Let's reduce that idea to basic language using some analogies: (It's very simplified and reduced, many details are omitted.)

Axioms are basic building blocks. Building blocks can be arranged and combined in all sort of ways, like a mosaic. You can chunk them and re-arrange them.

A dynamical system is a chaotic system that changes over time. Its compounds interact. These interactions correlate to the alterations in the dynamical system (compound = subordinate or detail, system = superordinate or whole/big picture)

-> (quantum) contextuality: [Quantum contextuality means the whole alters the details, as well as the details alter the whole. The system alters the compounds, and the compounds alter the system.] [Also: to understand quantum contextuality you can use the example of translating language: One word often has multiple meanings. It is ambigious. Which word is meant in that sentence? The right meaning of the word can be found when the context is analyzed. That is basically the principle behind quantum contextuality: (Also: Good read: https://www.quantamagazine.org/the-spooky-quantum-phenomenon-youve-never-heard-of-20220622/ )] {Further idea in my brain: What is the role of quantum contextuality in quantum error correction algorithms such as Bayesian Optimization?}

Well, back to axiomatization:

A system is a collection of interwoven building blocks. Axiomatization is a process of segmentation, of chunking, and of de-tangling the whole into its basic building blocks.
