Title: The singular support of an $\ell$-adic sheaf
(Submitted on 5 Sep 2023 (v1), last revised 11 May 2024 (this version, v3))
Abstract: We define the singular support of an $\ell$-adic sheaf on a smooth variety over any field. To do this, we combine Beilinson's construction of the singular support for torsion \'etale sheaves with Hansen and Scholze's theory of universal local acyclicity for $\ell$-adic sheaves.
