DUAL PROJECTION IN A TWO-DIMENSIONAL CURVED EXPANDING UNIVERSE

It is a well-known result that the scalar field is composed of two chiral particles (Floreanini–Jackiw particles) of opposite chiralities. Also, that a Siegel particle spectrum is formed by a nonmover field (a Hull's noton) and a FJ particle. In this work, we show that in a scalar field spectrum, in a curved expanding universe scenario, we find a different result, two dynamical chiral fields.
