In science:

Given a set of items A, let R be the relevant items, and let G be the bystander items.
On the critical exponents of random k-SAT
Thus partially-free is in fact a valid bystander rule.
On the critical exponents of random k-SAT
For the q -core and q -colorability, we also use the “partially-free” bystander rule, which in the context of graphs (and hypergraphs) declares an edge to be a bystander if one of its endpoints has degree 1.
On the critical exponents of random k-SAT
It is simple to check that partially-free is a valid bystander rule for these properties.
On the critical exponents of random k-SAT
Remark: We could in principle use instead other bystander rules.
On the critical exponents of random k-SAT
One possibility is to declare any clause that eventually gets resolved by repeated application of the pure literal rule to be a bystander.
On the critical exponents of random k-SAT
But it is easier to analyze the partially-free bystander rule, and our ob jective to provide a simple rigorous proof.
On the critical exponents of random k-SAT
Informally, Theorem 1 says that if there are many bystanders, then the transition cannot be too sharp.
On the critical exponents of random k-SAT
Let gm be the number of bystander items, and rm = m − gm the number of relevant items of fm .
On the critical exponents of random k-SAT
Since our sequence of items fm is already in a random order, we may instead pick and keep the first L relevant items of fm and the first b − L bystander items of fm .
On the critical exponents of random k-SAT
To apply Theorem 1 to k-SAT, we need to show that many clauses are bystanders, and to apply it to the q -core and q -colorability thresholds, we need to show that many edges are bystanders.
On the critical exponents of random k-SAT
To compute these we need to count more carefully the number of places α or β to which the two interacting particles may jump, given that two of the orbitals remain occupied by the two ‘bystanders’ during the interaction.

This allows us to include self energy and vertex corrections to all orders in a conserving approximation which becomes exact when the system is highly polarized, in the sense that the density of the bystander atoms is much smaller than the density of the 1 atoms.
