Description
The brief review and discussion of statement of some observational
problems of gamma-ray bursts (GRB), GRB host galaxies and star forming at
small and large redshifts: Are there similarities and differences between
GRB hosts and the typical galaxy population - this is currently the main
question for the study of GRB host galaxies. The direct connection between
long-duration GRBs and massive stars explosions, GRBs and some puzzles of
core-collapse supernovae are discussed. On model-independent observational
cosmological tests - GRB rate and star forming rate at high redshifts.
