Abstract
We discuss a generalization of constant-roll inflation models by using \(\beta\)-function formalism for inflation in such a way that the exact constant-roll condition is asymptotically satisfied near the fixed points of the \(\beta\)-functions, in other words, in deep inflationary phase. Several types of the \(\beta\)-functions and the corresponding inflaton potentials which satisfy the generalized constant-roll condition are analytically found.
