Blow up of solutions to semilinear wave equations. <i>Electronic Journal of Differential Equations, 2003</i>(53), pp. 1-5.1072-6691https://hdl.handle.net/10877/12993This work shows the absence of global solutions to the equation utt = ∆u + p-k |u|m, in the Minkowski space M0 = ℝ x ℝN, where m > 1, (N - 1)m < N + 1, and p is a conformal factor approaching 0 at infinity. Using a modification of the method of conformal compactification, we prove that any solution develops a singularity at a finite time.Text5 pages1 file (.pdf)enAttribution 4.0 InternationalBlow upConformal compactificationArticle
