• Resumen

  • We show that the Frenkel-Gross connection on Gm is physically rigid as Gˇ -connection, thus confirming the de Rham version of a conjecture of Heinloth-Ngô-Yun. The proof is based on the construction of the Hecke eigensheaf of a Gˇ -connection with only generic oper structure, using the localization of Weyl modules.
