A note on ultraviolet suppressed quasi-optimal domain wall fermions

Abstract

In a recent work Chiu proposed to modify domain wall fermions that allow in an optimal way fewer number of flavors than in the standard case. This is done using a variant of doamin wall fermions, the so-called truncated overlap fermions. In this note I discuss the possibility to implement his proposal for the original variant of domain wall fermions. I make also some remarks on dynamical simulations with ultraviolet suppressed domain wall fermions.
