No-homomorphism conditions for hypergraphs %K hypergraph homomorphism %K independing number %K Clique number %K chromatic number %K fractional chromatic number %R 10.22034/as.2018.1263 %X In this paper, we define some new homomorphism-monotone parameters for hypergraphs. Using these parameters, we extend some graph homomorphism results to hypergraph 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. %U https://as.yazd.ac.ir/article_1263_5837ea3e49312c8317d9598976971934.pdf
