Abstract: We adopt the idea of velocity averaging lemma to establish regularity for stationary linearized Boltzmann equations in a bounded convex domain. Considering the incoming data, with three iterations, we establish regularity in fractional Sobolev space in space variable up to order 1-. This take is based on a collaboration with Ping-Han Chuang, Chun-Hsiung Hsia, and Jhe-Kuan Su.
