摘要：In this talk we discuss a notion of Feynman geometry on which quantum field theories could be properly defined. A strong Feynman geometry is a geometry when the vector space of A_/infinity;structures is finite dimensional. A weak Feynman geometry is a geometry when the vector space of A_/infinity structures is infinite dimensional while the relevant operators are of trace-class. We construct families of Feynman geometries with "continuum" as their limit.
