»Enhanced ind-sheaves and the Tamarkin category«

Abstract:
To investigate not necessarily conic Lagrangian subsets in a cotangent bundle, Tamarkin introduced the Tamarkin category, also known as the category of enhanced sheaves. Guillermou-Schapira later revisited Tamarkin’s work and systematically studied the quotient category by torsion objects. D’Agnolo-Kashiwara defined the category of enhanced ind-sheaves by applying Tamarkin’s construction to the category of ind-sheaves and established their Riemann-Hilbert correspondence. In this talk, we explain that the $\mathbb{R}$-constructible objects in the category of enhanced ind-sheaves can be understood as $\mathbb{R}$-constructible objects in a certain quotient category of the Tamarkin category. This talk is based on joint work with Tatsuki Kuwagaki (Kyoto University) in progress.
