The Klein j-Function is not Pfaffian over the Real Exponential Field

arXiv:2311.06980

Abstract

James Freitag showed that the Klein j-function is not paffian over the complex numbers. We expand on this result by showing that a restriction of the Klein j-function to the imaginary interval (0, i) is not pfaffian over the real field exponential field in the sense of Miller and Speissegger.
