 In this talk, I would like to share some of my recent study on this problem. By introducing the modified Bessel function of second kind $K_\nu$, the blowup range is extended from $p_F(n)\leq p < p_s(n+2\mu)$ to $p_F(n)\leq p < p_s(n+\mu)$ for the subStrauss exponent. For the critical Strauss exponent, applying the plane wave fourmula and utilizing the limiting behavior of $K_\nu$, the desired lifespan estimate is obtained.
