Finite time blow up for critical wave equations in high dimensions
Borislav Yordanov,Qi S. Zhang +1 more
TL;DR: In this article, it was shown that solutions to the critical wave equation below can not be global if the initial values are positive somewhere and nonnegative, which is the case for the lower dimensional case.
Journal ArticleDOI
Finite-Time Blowup for Wave Equations with a Potential
Borislav Yordanov,Qi S. Zhang +1 more
TL;DR: Using this new method, blowup phenomenon for wave equations with a potential is established, which complements the recent interesting existence result by V. Georgiev and H. Heiming.
Journal ArticleDOI
Blow-up of solutions to critical semilinear wave equations with variable coefficients
Kyouhei Wakasa,Borislav Yordanov +1 more
TL;DR: In this article, the critical case p = p 0 (n) of Strauss' conjecture was verified, where n ≥ 2 and the perturbations of the Laplace operator decay exponentially fast at infinity.
Journal ArticleDOI
The energy decay problem for wave equations with nonlinear dissipative terms in Rn
TL;DR: In this article, the authors studied the asymptotic behavior of energy for wave equations with nonlinear damping and showed a polynomial decay rate of energy under the condition 1 < m < (n + 2) /(n + 1)
