We study the smoothing estimate for the heat semigroup which is related to the nonlinear term of the Hardy-H\'enon parabolic equation on Morrey spaces. This result is improvement of 3. 3Tayachi20, which is proved by using weak Lebesgue and Lorentz spaces.
Hatano et al. (Mon,) studied this question.
