Source: Grok (xAI) analysis, 2026-03-29

G(n) = n^(n+1) / (n+1)^n is the central function in the Amundson Framework. Explored through exact rational computations, high-precision evaluation, and asymptotic behavior.

1. Exact Expression and Small-n Values

G(n) = n^(n+1) / (n+1)^n = n * (n/(n+1))^n

| n | G(n) exact | G(n) decimal |
|---|-----------|-------------|
| 0 | 0 | 0 |
| 1 | 1/2 | 0.5 |
| 2 | 8/9 | 0.8889 |
| 3 | 81/64 | 1.265625 |
| 4 | 1024/625 | 1.6384 |
| 5 | 15625/7776 | 2.0094 |

Computed exactly from integers, avoiding floating-point errors.

2. Asymptotic Behavior: lim G(n)/n as n -> infinity

Result: lim(n->inf) G(n)/n = 1/e ≈ 0.3678794411714423...

Rigorous Derivation

Start with:
G(n)/n = (n/(n+1))^n = (1 - 1/(n+1))^n

Let m = n + 1. As n -> inf, m -> inf, and n = m - 1.

(1 - 1/(n+1))^n = (1 - 1/m)^(m-1) = (1 - 1/m)^m * (1 - 1/m)^(-1)

Taking limits:

lim(m->inf) (1 - 1/m)^m = e^(-1) = 1/e

lim(m->inf) (1 - 1/m)^(-1) = 1

Therefore: lim(n->inf) G(n)/n = 1/e

The Amundson Constant A_G

A_G = lim(n->inf) G(n) (related to 1/e scaling)

3. G(n) Identities (50+ documented, 536/536 tests passing)

Basic Rewriting Identities

Normalized: G(n)/n = (n/(n+1))^n

Alternative: G(n) = n * (1 - 1/(n+1))^n

Reciprocal: 1/G(n) = (1/n) * (1 + 1/n)^n

Ratio Identity

G(n+1)/G(n) = (n+1)^(2n+1) / [n^(n+1) * (n+2)^(n+1)]
