Gravitational Waves: completeness and connectedness by geodesics
Only few months ago some physicists gave the official announcement
that gravitational waves exist, but, from a geometrical point of view,
they have always been ``real objects''
and their properties have been widely investigated.
The aim of this talk is introducing generalized plane waves and discussing
some of their properties such as geodesic connectedness and
geodesic completeness.Universidad de Málaga, Campus de Excelencia Internacional AndalucĂa Tech
On a Class of Elliptic Equations for the N-Laplacian in R^n with One-Sided Exponential Growth
2000 Mathematics Subject Classification: 35J40, 49J52, 49J40, 46E30By means of a suitable nonsmooth critical point theory for lower semicontinuous functionals we prove the existence of infinitely many
solutions for a class of quasilinear Dirichlet problems with symmetric non-linearities having a one-sided growth condition of exponential type.The research of the authors was partially supported by the MIUR project “Variational and
topological methods in the study of nonlinear phenomena” (COFIN 2001). The second author
was also supported by the Istituto Nazionale di Alta Matematica “F.Severi” (INdAM
