Many processes in physics, computation, AI systems, and numerical methods aren’t linear flows — they are **two-phase recursive loops**. They iterate forward through an expansion process, then return through a contraction or update step that is meant to “undo” or counterbalance the forward map.
Examples include:
* signal processing pipelines (operator + adjoint) * energy-stabilized iterative solvers * recurrent or reflective AI reasoning loops * delayed feedback physical systems * simulated physical fields with forward + backward operators
In these systems, a natural question arises:
> **What guarantees that a recursive loop actually closes, rather than drifting or accumulating error across cycles?**
Bird’s Law proposes a simple, falsifiable mathematical condition governing that closure.
---
## **2. The Core Claim**
Let a recursive process alternate between:
* a **forward/expansion** operator (R) * an **adjoint/contraction** operator (R_{\text{adj}})
Let (S(\Psi)) be any energy-like functional or quadratic measure over the state (\Psi).
Define the per-phase signed difference:
``` ΔSₖ = S(Ψₖ₊₁) − S(Ψₖ) σₖ = +1 for forward phases, −1 for adjoint phases ```
Then define the loop-global invariant:
``` I_rec = Σₖ [ σₖ * ΔSₖ ] ```
The central invariant:
> **Bird’s Law (Closure Criterion)** > **The recursive loop closes (I_rec → 0) iff the adjoint operator is the true adjoint of the forward operator.**
Equivalently:
``` I_rec = 0 ⇔ R_adj = R* ```
This is the mathematical heart of the work: recursive stability ↔ adjoint symmetry.
---
## **3. Numerical Evidence**
To test the invariant, I constructed simple but explicit FFT-based recursion loops:
* signal passes through forward operator (convolution with kernel h) * then through contraction operator (reverse(h) or intentionally mismatched h) * energy differences are summed with phase-sign weights * invariant behavior is measured
The results were stable across:
* Gaussian, sinc, and exponential kernels * sine waves and noise * multiple sampling rates * guard-band trimmed energy measures
The divergence is immediate and consistent. The invariant never “accidentally” goes to zero in mismatched cases.
---
## **4. Why This Might Matter to LessWrong**
LessWrong has long explored:
* reflectivity * fixed points of thought * consistency requirements in recursive cognition * dual-phase optimization * stability of feedback loops * error accumulation under repeated self-reference
Bird’s Law proposes a crisp mathematical property that arises **whenever a system tries to return through the adjoint of its own update process** — which includes:
* certain recurrent reasoning architectures * multi-agent update models * self-correcting logic structures * iterative reflective or meta-cognitive algorithms * consistency conditions for interpretability checks * universes described by expansion–contraction symmetry
This makes Bird’s Law relevant to:
### **AI alignment**
Recursive reasoning loops used in planning, self-critique, chain-of-thought verification, rollouts, or world-model corrections implicitly depend on an “adjoint-like” update to undo or counterbalance local drift.
Bird’s Law gives a sharp condition for when those updates will actually stabilize.
### **Reflective cognition**
If cognitive steps have forward and adjoint (reflective) phases, then stability under self-reference requires something equivalent to the adjoint condition.
### **Error accumulation and drift**
Many agent models assume stable returns to baseline after a reflective cycle; Bird’s Law identifies when drift is structurally inevitable.
---
## **5. What I’m Looking For From the LW Community**
I’m explicitly not asking anyone to accept the broader cosmological framing (though the paper develops one). This LessWrong post is narrowly about **recursive invariance and adjoint symmetry**.
I’m looking for critique on:
1. **Does the “if and only if” condition hold under general operator assumptions?** (Bounded linear operators, real/complex inner product spaces, etc.)
2. **Are there existing invariants in operator theory, monotone operator analysis, or adjoint-gradient systems that already cover this behavior?** If so, I want to know.
3. **Does the loop-global invariant I_rec behave as I describe under conventional functional analysis?**
4. **Are there edge cases where the adjoint is matched but the invariant would not vanish?**
5. **Does this have implications for recursive alignment architectures or reflective cognition models?** I’m open to being corrected here.

## **7. Closing**
Recursive structures dominate physical, computational, and cognitive systems. If the adjoint condition truly governs recursive closure across domains, then this invariant may be useful as a diagnostic tool — or it may need to be folded into existing operator theory.
I welcome rigorous critique, counterexamples, related theorems, or suggestions on how this might integrate with known recursive stability theory.

## **1. Motivation**
Many processes in physics, computation, AI systems, and numerical methods aren’t linear flows — they are **two-phase recursive loops**. They iterate forward through an expansion process, then return through a contraction or update step that is meant to “undo” or counterbalance the forward map.
Examples include:
* signal processing pipelines (operator + adjoint)
* energy-stabilized iterative solvers
* recurrent or reflective AI reasoning loops
* delayed feedback physical systems
* simulated physical fields with forward + backward operators
In these systems, a natural question arises:
> **What guarantees that a recursive loop actually closes, rather than drifting or accumulating error across cycles?**
Bird’s Law proposes a simple, falsifiable mathematical condition governing that closure.

## **2. The Core Claim**
Let a recursive process alternate between:
* a **forward/expansion** operator (R)
* an **adjoint/contraction** operator (R_{\text{adj}})
Let (S(\Psi)) be any energy-like functional or quadratic measure over the state (\Psi).
Define the per-phase signed difference:
```
ΔSₖ = S(Ψₖ₊₁) − S(Ψₖ)
σₖ = +1 for forward phases, −1 for adjoint phases
```
Then define the loop-global invariant:
```
I_rec = Σₖ [ σₖ * ΔSₖ ]
```
The central invariant:
> **Bird’s Law (Closure Criterion)**
> **The recursive loop closes (I_rec → 0) iff the adjoint operator is the true adjoint of the forward operator.**
Equivalently:
```
I_rec = 0 ⇔ R_adj = R*
```
This is the mathematical heart of the work:
recursive stability ↔ adjoint symmetry.

## **3. Numerical Evidence**
To test the invariant, I constructed simple but explicit FFT-based recursion loops:
* signal passes through forward operator (convolution with kernel h)
* then through contraction operator (reverse(h) or intentionally mismatched h)
* energy differences are summed with phase-sign weights
* invariant behavior is measured
The results were stable across:
* Gaussian, sinc, and exponential kernels
* sine waves and noise
* multiple sampling rates
* guard-band trimmed energy measures
Matched adjoint:
* **I_norm ≈ 0.03**
* stable, loop closes
Broken adjoint:
* **I_norm ≈ 1.8–2.0**
* divergence grows ~60×
* loop fails
The divergence is immediate and consistent.
The invariant never “accidentally” goes to zero in mismatched cases.
