Abstract

We consider semilinear wave equations with focusing power nonlinearities in odd space dimensions d5d \geq 5. We prove that for every p>d+3d1p > \frac{d+3}{d-1} there exists an open set of radial initial data in Hd+12×Hd12H^{\frac{d+1}{2}} \times H^{\frac{d-1}{2}} such that the corresponding solution exists in a backward lightcone and approaches the ODE blowup profile. The result covers the entire range of energy supercritical nonlinearities and extends our previous work for the three-dimensional radial wave equation to higher space dimensions.
