Ample divisors on the blow up of P at points
In this note we will prove a theorem on divisors on the blow up of P at points which extends a theorem of G. Xu [Xu] on the blow up of P. The central idea of the proof works for any dimension and therefore opens the doors to a generalization of the theorem to higher dimension, once one overcomes certain technical difficulties that arise. Basically we will give a new proof of Xu’s theorem that w...
متن کاملOn Blow-up at Space Infinity for Semilinear Heat Equations
We are interested in solutions of semilinear heat equations which blow up at space infinity. In [7], we considered a nonnegative blowing up solution of ut = ∆u+ u, x ∈ R, t > 0 with initial data u0 satisfying 0 ≤ u0(x) ≤ M, u0 ≡ M and lim |x|→∞0 = M, where p > 1 and M > 0 is a constant. We proved in [7] that the solution u blows up exactly at the blow-up time for the spatially constant solution...
متن کاملBlow { up Analysis on the Heat
By blow{up analysis on the descending ow for the Yamabe quotient of a compact Reimannian manifold (M n ; g); n 3 , we prove that the ow globally exists and subconverges to u1 such that the scalar curvature of u 4 n?2
متن کاملBlow up Dynamic and Upper Bound on the Blow up Rate for critical nonlinear Schrödinger Equation
We consider the critical nonlinear Schrödinger equation iut = −∆u − |u| 4 N u with initial condition u(0, x) = u0 in dimension N . For u0 ∈ H1, local existence in time of solutions on an interval [0, T ) is known, and there exists finite time blow up solutions, that is u0 such that limt→T<+∞ |ux(t)|L2 = +∞. This is the smallest power in the nonlinearity for which blow up occurs, and is critical...
