Query: Analytic digraphs of uncountable Borel chromatic number under injective
  definable homomorphism   We study the analytic digraphs of uncountable Borel chromatic number on
Polish spaces, and compare them with the notion of injective Borel
homomorphism. We provide some minimal digraphs incomparable with G 0. We also
prove the existence of antichains of size continuum, and that there is no
finite basis. 2010 Mathematics Subject Classification. 03E15, 54H05
