Refined blowup analysis and nonexistence of Type II blowups for an energy critical nonlinear heat equation

Kelei Wang, Juncheng Wei

We consider the energy critical semilinear heat equation $$ \left\{\begin{aligned} &\partial_t u-Δu =|u|^{\frac{4}{n-2}}u &\mbox{in } {\mathbb R}^n\times(0,T),\\ &u(x,0)=u_0(x), \e…
