ABSTRACT
Dynamical properties of topological defects in a twodimensional 
complex vector field are considered. These objects naturally arise 
in the study of polarized transverse light waves. Dynamics is 
modeled by a Vector Complex Ginzburg-Landau Equation with  
parameter values appropriate for linearly polarized laser 
emission. Creation and annihilation processes, and 
selforganization of defects in lattice structures, are described. 
We find ``glassy" configurations dominated by vectorial defects 
and a melting process associated to topological-charge unbinding. 

In this directory, vectorshort.tex contains the main paper (in LATeX)
the .ps.gz are the gzipped postscript figures. Once gunzipped, they 
are called in from the LATeX
paper.  vectorshort.ps is the postscript file containing the full paper:
text+figures. 
The file vectorshort.uu is a c-shell script containing gzipped and
tarred versions of all the files. It will unpack itself in a UNIX system
by typing csh vectorshort.uu
