Spectral Picard-Vessiot fields for Algebro-geometric Schrödinger operators

Juan J. Morales-Ruiz, Sonia L. Rueda, Maria-Angeles Zurro

This work is a galoisian study of the spectral problem $L\Psi =\lambda \Psi$, for algebro-geometric second order differential operators $L$, with coefficients in a differential field, whose fiel…
