我们计算了边界爆破解的完全渐近展开式(见方程)。(1),对于任何非线性f,我们的方法使我们能够陈述关于解的唯一性和径向对称性的尖锐的定性结果,以及关于爆破率是普适的非线性的特征。最后,我们更详细地研究了标准非线性项f(U)=up,p>1。
We calculate the full asymptotic expansion of boundary blow-up solutions (see Eq. (1) below), for any nonlinearity f. Our approach enables us to state sharp qualitative results regarding uniqueness and radial symmetry of solutions, as well as a characterization of nonlinearities for which the blow-up rate is universal. Lastly, we study in more detail the standard nonlinearities f(u)=up, p>1.
