Abstract
The phase structure and IR properties of the higher-derivative quantum gravity (QG) with scalar matter in 4 - epsilon dimensions are investi gated. The appearance of a few fixed points of the renormalization gro up (one of them is an infrared stable fixed point) is numerically show n. The new fixed points in 3 dimensions are associated with QG. The na ture of phase transitions at nonzero temperature is discussed, and the improved effective potential is calculated.
