In quantum field theory the time slice axiom is an additional axiom often considered on top of the basic Haag-Kastler axioms: it encodes the property that the time evolution of the classical field theory underlying a QFT is governed by well-defined initial value problems.
A local net of observables satisfies the time slice axiom if whenever a causal inclusion of Lorentzian spaces is such that contains a Cauchy surface of then is an isomorphism.
