Abstract
Let be a complete -factorial toric variety. We explicitly describe the space and the cup product map in combinatorial terms. Using this, we give an example of a smooth projective toric threefold for which the cup product map does not vanish, showing that in general, smooth complete toric varieties may have obstructed deformations.
