The Annales de l’Institut Fourier aim at publishing original papers of a high level in all fields of mathematics, either in English or in French.The Editorial Board encourages submission of articles containing an original and important result, or presenting a new proof of a central result in a domain of mathematics. Also, the Annales de l’Institut Fourier being a general purpose journal, highly specialized articles can only be accepted if their exposition makes them accessible to a larger audience.
