单位球中边界爆破解的渐近性、唯一性和对称性

Boundary blow-up solutions in the unit ball : asymptotics, uniqueness and symmetry

Ovidiu Costin, Louis Dupaigne

摘要:

对于任意非线性项f,我们计算了边界爆破解的完全渐近展开。我们的方法使我们能够状态尖锐的定性结果的唯一性和径向对称性的解决方案,以及一个非线性的爆破率是普遍的表征。最后,我们详细研究了标准非线性函数f(u)= u^p,p > 1

英文摘要:

We calculate the full asymptotic expansion of boundary blow-up so- lutions, for any nonlinearity f . Our approach enables us to state sharp qualitative results regarding uniqueness and ra- dial symmetry of solutions, as well as a characterization of nonlinearities for which the blow-up rate is universal. At last, we study in more detail the standard nonlinearities f (u) = u^p, p > 1
