Chain (for example in sudoku) is a sequence of connected implications:
x1 -> x2 -> x3 ... -> xn
Set of solutions:
1. false -> false -> ... -> false -> true -> true -> ... -> true
2. all variables equal

All other stuff you can found on a picture.

If anyone of you already seen things like that please recommend me books or links to that.

Also you can contribute to this idea, to make it more rigorous or general.
