Search for new variable stars at the borders of the globular clusters NGC 3201

By means of the same method previously used with ω Centauri a search for new variable stars at the borders of the globular cluster NGC 3201 has been made. To this end the author had at disposal 98 blue photographic plates taken with the "Carte du Ciel" astrograph of the La Plata Observator...
