Frenkel-Gross' irregular connection and Heinloth-Ngô-Yun's are the same

Abstract

We show that the irregular connection on $\bbG_m$ constructed by Frenkel-Gross (2009) and the one constructed by Heinloth-Ngô-Yun (arXiv:1005.2765) are the same, which confirms the Conjecture 2.14 of arXiv:1005.2765.
