A new critical exponent for the semilinear damped wave equation with Hartree-type nonlinearity and initial data from homogeneous Besov spaces
A new critical exponent p_Fuji((n+2β)/(2+γ)) = 1 + (4+2γ)/(n+2β) separates global small-data solutions from finite-time blow-up for the damped wave equation with Hartree nonlinearity in homogeneous Besov spaces.
