How to understand the periodic boundary conditions applied in Lmtx and Gmtx?

Hi, thanks for your awesome work! I read your blog (https://medium.com/swlh/create-your-own-plasma-pic-simulation-with-python-39145c66578b) and the correspondign code, but I can not understand the the periodic boundary conditions applied in Lmtx and Gmtx, could you explain it in detail? By the way, the Gmtx in the blog seems uncorrect:
