ERE 2004

The Spanish Relativity Meetings (E.R.E.) are annual gatherings which take place in some spanish city and to which most spanish relativitists and cosmologists usually attend. The idea is that at least one senior member of each active spanish group working on gravitation and related matters explains the main interests and achievements of his/her group and interacts with other colleagues in a friendly and usually very pleasant atmosphere. These meetings are also an invaluable place where young spanish students can learn the latest developments and train themselves in the english language at the same time that they present their own research progress and results.
