Classification of positive solutions of p -Laplace equation with a growth term

Matteo Franca (2004)

Archivum Mathematicum

We give a structure result for the positive radial solutions of the following equation: Δ p u + K ( r ) u | u | q - 1 = 0 with some monotonicity assumptions on the positive function K ( r ) . Here r = | x | , x n ; we consider the case when n > p > 1 , and q > p * = n ( p - 1 ) n - p . We continue the discussion started by Kawano et al. in [KYY], refining the estimates on the asymptotic behavior of Ground States with slow decay and we state the existence of S.G.S., giving also for them estimates on the asymptotic behavior, both as r 0 and as r . We make use of a Emden-Fowler transform...

Gevrey hypoellipticity for a class of degenerated quasi-elliptic operators

Genadij O. Hakobyan, V. N. Margaryan (2003)

Commentationes Mathematicae Universitatis Carolinae

The problems of Gevrey hypoellipticity for a class of degenerated quasi-elliptic operators are studied by several authors (see [1]–[5]). In this paper we obtain the Gevrey hypoellipticity for a degenerated quasi-elliptic operator in 2 , without any restriction on the characteristic polyhedron.
