چکیده
|
In this paper, we dene some new homomorphism-monotone parameters for hy- pergraphs. using these parameters, we extend some graph homomorphism results to hyper- graph case. also, we present some bounds for some well-known invariants of hypergraphs such as fractional chromatic number,independent numer and some other invariants of hyergraphs, in terms of these parameters.
