SINGULARITIES FORMED BY THE FOCUSING OF CYLINDRICAL NULL FLUIDS

Motivated by the recent studies of the late stages of gravitational co llapse, the collision and interaction of cylindrically symmetric null fluids are studied. By investigating analytic models, we find that a n aked singularity can be developed. This singularity is different from the ones found previously in the sense that it is solely formed by the mutual focus of the null fluids.
