Abstract: We give an estimation for the arithmetic genus of an integral space curve which is not contained in a surface of degree $k-1$. Our main technique is the Bogomolov-Gieseker type inequality for $\mathbb{P}^3$ proved by Macri.
Keywords: space curve; arithmetic genus; Bridgeland stability; Bogomolov-Gieseker inequality
