Primordial Black Hole (PBH) is an important object due to its potential possibility of acting as dark matter and explaining supermassive astrophysical objects, so how to generate PBHs becomes an interesting topic to cosmologists. In this talk, I will discuss two ways of PBHs generation from a single field inflation model, especially the way with the modified dispersion relation discussed recently can be realized by the model inspired from the Galileon theory. Moreover, I will also discuss about the induced gravitational waves generated in these ways, which is to be constrained by the current NANOGrav data.
