The journal "AAPP Atti della Accademia Peloritana dei Pericolanti, Classe di Scienze Fisiche, Matematiche e Naturali" is multi- and inter-disciplinary in nature, covering a wide range of fields including mathematics, computer science, physics, chemistry, biology, earth sciences, and their intersections. It also addresses topics related to the history of science. The transactions of the Pelorian Academy began as periodic news sheets containing notes presented by members of the various divisions organized by subject area. The publication of these notes for the Division of Mathematical, Physical and Natural Sciences is managed by an Editorial Committee, which consists of the Director of the division (Chairman), the Vice-Director, the Secretary, and two or more additional members. In addition to original research articles, the journal accepts texts from conferences and invited talks held at the Academy, which are published in a separate section. Occasionally, single monographic supplements are published, compiling reports and communications presented at congresses, symposia, seminars, study meetings, and other scientific events organized by the Academy or under its patronage. Since 2004, these transactions have been published online as an open access electronic journal.
