L(p, q)-Labeling and Integer Flow on Planar Graphs

The Computer Journal, 2012
Given a graph G and two non-negative integers p and q, an L(p, q)-labeling c of G is an assignment of non-negative integers to the vertices of G such that, for any two vertices u and v, |c(u)-c(v)| ≥ p if d(u, v)=1 and |c(u)-c(v)| ≥ q if d(u, v)=2. The L(p, q)-labeling problem arises from a variation of the channel assignment problem.

Approximation by Baskakov-Durrmeyer operators based on (p,q)-integers

Mathematica Slovaca, 2018
AbstractIn the present paper, we introduce a new sequence of linear positive operators based on (p,q)-integers. To approximate functions over unbounded intervals, we introduce Baskakov-Durrmeyer type operators using the (p,q)-Gamma function. We investigate rate of convergence of new operators in terms of modulus of continuities and obtain their ...
