Resumen:
Wormholes are solutions of gravitational theory which consist of two regions joined by a throat, usually giving a multiple connected topology. In general relativity theory, these kind of solutions have the characteristic that they require the presence of exotic matter, which violates the usual energy conditions. In this talk, spherical thin shell wormholes with exotic matter in the form of a Chaplygin gas will be considered, with an analysis of their stability under perturbations preserving the symmetry. It will be shown that there are geometries for which exist stable solutions for some values of the parameters.
