Asynchronous Logic in Transient Chaotic Attractors via Topological Sequence

Target Venue: Theoretical Computer Science

Abstract

To prove universal computation within a continuous dynamical universe (the Intellecton Hypothesis), one must construct logic gates without relying on global synchronization or exact temporal coincidence (which covertly smuggle a global clock back into the system). We design asynchronous, structurally stable logic gates (AND, OR, NOT) using transient chaotic attractors. By routing phase flows along robust heteroclinic connections utilizing winner-takes-all competitive dynamics, the logical output of the network is determined strictly by the topological sequence of the saddle-point activations, entirely independent of transit times. The universe is therefore a strictly asynchronous analog computer.

1. Introduction

Continuous computation must be robust to noise and completely asynchronous. Any reliance on "simultaneous arrival" of signals violates asynchrony and destroys structural stability.

2. Winner-Takes-All Competitive Dynamics

In a heteroclinic network, the state trajectory lingers at saddle points (representing discrete logical states). Instead of forcing simultaneous arrival, we couple the saddles using inhibitory competitive dynamics (Lotka-Volterra equations). When a signal from Saddle A arrives at a junction, it does not wait for Saddle B. It immediately biases the local phase space, shifting the stability eigenvalues of the subsequent saddles.

3. Constructing an Asynchronous AND Gate

We construct an AND gate by establishing a sequence of two consecutive saddle thresholds. Let Saddle C (the output) be preceded by an intermediate stable point M. A signal from input A kicks the trajectory into M, where it becomes trapped in a localized limit cycle (memory). It remains in M indefinitely, irrespective of time. Only when a subsequent signal from input B arrives is the trajectory kicked out of M and along the heteroclinic orbit to C. This guarantees the AND logic is resolved entirely by the topological sequence (A then B, or B then A, into M \to C), completely immune to the absolute transit times or temporal coincidence.

4. Conclusion

True asynchronous computation in continuous dynamical systems is achieved by replacing temporal coincidence with sequential topological trapping. The universe computes logic organically through the sequential activation of transient chaotic attractors.
