= Field configuration eigenstate
{synonym}
A <scalar field configuration eigenstate> assigns eigenvalues of the equal-time field operator at every spatial point. These generalized states play the role of position eigenstates for a system of infinitely many coordinates. Inserting their regulated completeness relations on time slices constructs the <scalar field path integral>.
