Endoscopic lifting of simple supercuspidal representations of unramified \(\mathrm{U}_N\) to \(\mathrm{GL}_N\) (Q2279519)

From the abstract: We compute the characters of simple supercuspidal representations of a twisted \(\mathrm{GL}_N\) and an unramified quasi-split unitary group \(\mathrm{U}_N\) over a \(p\)-adic field. Comparing them by the endoscopic character relation, we determine the endoscopic lifts of simple supercuspidal representations of \(\mathrm{U}_N\) to \(\mathrm{GL}_N\), under the assumption that \(p\) is not equal to 2.
