Estimados, Después de meses de estar inhabilitada (por mi culpa), esta lista de distribución de emails "graficas(a)xamanek.izt.uam.mx" está funcionando de nuevo. Les recuerdo que esta lista es para: "Anunciar congresos y talleres y otras actividades de la comunidad de combinatoria (y gráficas y teoría de la computación y geometría computacional, etc.) en México. Bienvenidos también anuncios sobre convocatorias de plazas." Si gustan difundir mensajes relevantes para la comunidad de combinatoria en México, pueden enviarlos a ese email (desde una cuenta de email que esté suscrita a la lista). La lista está moderada por default para evitar spam. La página web para administrar sus suscripción (suscribirse, darse de baja, etc.) es: https://xamanek.izt.uam.mx/graficas/ Nos vemos pronto en el coloquio. Saludos cordiales. Miguel Pizaña
