<Juan Maldacena> calculated three-point correlations of primordial scalar and tensor fluctuations in single-field <cosmic inflation>. His 2003 analysis gave explicit leading slow-roll predictions for <primordial non-Gaussianity> and showed that certain squeezed limits are fixed by the scale dependence of the two-point spectrum.<Non-Gaussian features of primordial fluctuations in single field inflationary models by Juan Maldacena>[Abstract and section 4: three-point functions and long-wavelength limits]{ref}
A <squeezed bispectrum configuration> compares one long <wavelength> with two short ones. In the applicable single-field regime, the long fluctuation acts locally as a coordinate rescaling, producing the <single-field inflation squeezed-limit consistency relation>. The statement depends on the inflationary model and limiting assumptions, rather than applying to every primordial three-point function.
