    "abstract": "In [1] it was shown that the Kochen Specker theorem can be written in terms\nof the non-existence of global elements of a certain varying set over the\npartially ordered set of boolean subalgebras of projection operators on some\nHilbert space. In this paper, we show how obstructions to the construction of\nsuch global elements arise, and how this provides a new way of looking at\nproofs of the theorem.",
