Abstract:
We present investigations of lens phenomenological properties of cosmic
strings for deep galaxy surveys. General results that have obtained for lineic
energy distribution are presented first. We stress that generically the local
convergence always vanishes in presence of strings although there might be some
significant distortions. We then propose a simplified model of strings, we call
``Poisson strings'', for which exhaustive investigations can be done either
numerically or analytically.
