States in the phase space formulation of quantum mechanics
We propose several practical criteria how to recognise functionals representing states in the phase space formulation of quantum mechanics. After minor modifications these criteria can be applied to check positivity of any functions from an algebra with the Weyl type $*$ -- product.
