چكيده فارسي :
In this paper, by reviewing the concept of covering maps and semicovering maps, we de ne and motivate (G;H)-(semi) covering map. Also we investigate the properties of (G;H)-(semi) covering map. For example, if p : ~X ..! X is a (G;H)-(semi) covering map and is a path in ~X with starting at x~0 and (1) = x, then p is an ( ..1G ; (p )..1H(p ))-(semi) covering map.
