Abstract: Consider the energy subcritical defocusing semilinear wave equation with pure power nonlinearity. By introducing new weighted vector fields as multipliers, we obtain improved time decay for the potential energy, which leads to the improved scattering results and pointwise decay estimates for the solutions. These are based on joint works with Dongyi Wei.
