GapProperties extends the gap display function from integer Z to real arguments and proves its monotonicity, concavity, and diminishing-increment properties. Mass-ladder derivations in electron and lepton necessity proofs cite these results to justify continuous approximations. The module consists of direct algebraic lemmas and standard real-analysis arguments on the extended function.

claimThe real extension $F:\mathbb{R}\to\mathbb{R}$ of the gap function satisfies $F(0)=0$, is strictly increasing and strictly concave on $[0,\infty)$, obeys $F(x+1)-F(x)$ strictly decreasing, and meets the explicit bounds $F(24)<F(276)<F(1332)$.

background

The gap function is introduced in RSBridge.Anchor as the display function $F(Z)=\ln(1+Z/\phi)/\ln\phi$ that converts the charge-indexed integer $Z_i$ into a real rung on the phi-ladder. Constants supplies the underlying time quantum $\tau_0=1$ tick. GapProperties extends this $F$ from integers to reals precisely to support concavity statements required downstream.

proof idea

The module proves a chain of lemmas by direct substitution and differentiation: gap_zero and gap_eq_log_phi_add_sub_one establish the base value and logarithmic identity; gap_strictMono_on_nonneg and gapR_nat give monotonicity; gap_24_lt_gap_276 and gap_276_lt_gap_1332 supply concrete comparisons; strictConcaveOn_gapR_Ici and gap_second_difference_neg establish concavity via the second-difference test.

why it matters in Recognition Science

These analytic properties feed directly into ElectronMass.Necessity (T9) and LeptonGenerations.Necessity (T10), where they justify the inequalities that close the forcing chain from T8 ledger quantization to forced lepton masses. The module supplies the continuous bridge between the discrete Z-map of Anchor and the real-valued mass formulas needed for the necessity arguments.
