Based on the biased centrosymmetric photorefractive media, we investigate numerically the propagation and interaction properties of Airy-Gaussian beams. The single Airy-Gaussian beam forms the one-component breather with the help of the photorefractive nonlinearity. The interaction properties of two Airy-Gaussian beams can be controlled by adjusting the relative parameters, such as photorefractive nonlinearity, transverse distance and relative phase of two incident beams. The two-component breather with ladder structure can be observed for both the in-phase and out-of-phase cases when the self-acceleration property is balanced by the photorefractive nonlinearity. The one- or three-component breathers can be observed for the in-phase case only when the transverse distance takes a certain range. [ABSTRACT FROM AUTHOR]
