# A good book for the p-fractional Laplacian

Can anyone suggest a good book or a nice self contained article for the p-fractional Laplacian for beginners. I am interested in the existence, regularity of weak solution of the following equation $$(- \Delta)_{p}^s u = f(x, u)\quad \text{in } \Omega, u=0 \quad \text{in } \mathbb R^N\setminus \Omega,$$ where $$\Omega$$ is a bounded domain. Thank you.
