Distance-two labelings of digraphs

G. J. Chang, J. -J. Chen, D. Kuo +1

For positive integers $j \geq k$ , an $L (j, k)$ -labeling of a digraph $D$ is a function $f$ from $V (D)$ into the set of nonnegative integers such that $∣ f (x) - f (y) ∣ \geq j$ if $x$ is adja…

Running spectral index and mode-mode correlation of inflationary perturbations from off-equilibrium effects

Da-Shin Lee, Li-Zhi Fang, Wolung Lee +1

We study the off-equilibrium effects of inflaton on the dynamics of primordial perturbations in the O(N) model. A self-consistent off-equilibrium formalism is employed to investiga…
