How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
The proposed small-gamma centered-adjacency tail has the opposite limit
Statement
Fix . For every even integer with , where is the natural logarithm, set . Let be the symmetric adjacency matrix with zero diagonal of , the loop-free simple graph on whose edge indicators are mutually independent Bernoulli variables. Let be the all-ones matrix, and let denote the operator norm for the Euclidean inner product on . Then , , and Here . The probability on the left tends to one through even at this one fixed value of .
Facts & Assumptions
Throughout the facts and proof, set , the least integer at least , as in the logarithmic parameter lemma (Explicit parameters for the small-gamma logarithmic density).
A vertex of degree at least forces (A centered adjacency column retains a high-degree lower bound).
For this same , the parameters satisfy and (Explicit parameters for the small-gamma logarithmic density).
A vertex of degree at least occurs with probability at least , tending to one (Independent cross-degrees produce a large degree at logarithmic density).
For nonnegative , is bounded below by every finite partial sum of its positive series (The real exponential function and the number e by a power series).
The exponential is positive and (The exponential is positive and satisfies exp(-x)=1/exp(x)).
The exponential is strictly increasing (The exponential function is strictly increasing).
For positive , the real power equals (Real powers for positive bases, with the zero-base positive-exponent convention).
The law is the finite simple graph on with mutually independent Bernoulli edge indicators, one for each two-element vertex subset (The Erdős-Rényi finite random graph G(n,p)).
For a matrix acting on the Euclidean inner product space , (The operator norm is zero on the zero domain and otherwise is max_‖ v‖=1‖ Tv‖).
An event is a subset of the finite outcome space and its probability is the sum of its nonnegative outcome weights, whose total is one. Consequently , and whenever (Finite probability spaces, outcome weights, events, and event probabilities).
Two distinct vertices are adjacent when they form an edge; the degree of a vertex is the cardinality of its open neighborhood, the set of its adjacent vertices (Adjacency, incidence, open and closed neighbourhoods, vertex degree, minimum degree and maximum degree).
Proof
Given: The objects and hypotheses in the Statement, with defined in Facts & Assumptions.
Goal: Prove the asserted conclusions.
The hypotheses of the parameter and amplification lemmas hold since , with the same and graph law [F8]. On the degree event from [F3], with degree understood as in [F12], [F1] and [F2], with the norm convention [F10], give . The strict comparison follows by squaring positive quantities: . The degree event is therefore contained in the asserted norm event. By [F11], its probability lower bound and limit from [F3] transfer to the norm event, whose probability is at most one. Finally [F2] gives and .
Since , [F4] gives . By [F5], the probability lower bound is greater than . Meanwhile , so [F4], [F5], [F6], and [F7] give . These strict and nonstrict comparisons prove the entire chain.
