Transfer theorem converts max-degree independence bounds to average-degree bounds for hereditary uniform hypergraphs, with applications to cycle-free graphs and bounded-clique graphs.
For p = d/n the r-th power has maximum degree ~ log n over (r+1)-fold log and chromatic number sandwiched between the maximum degrees of the floor(r/2) and (r-1) powers plus one (equality at r=2); for d = omega(log n) up to n^{1/r-Omega(1)} the chromatic number is Theta(d^r / log d).
New degree-sequence lower bounds on hard-core independent set sizes via multivariate local occupancy and spectral analysis.
