Weak and strong quantum vacuum: Properties of the different vacua

The ideas, definitions, and results of Castagnino and of Castagnino and Mazzitelli are improved and developed in a more general geometry. Also, a more satisfactory definition of the weak vacuum (defined by the coincidence of a local and a global property up to the lowest order) is introduced which y...
