# Special Issues

*Symmetry* runs special issues to create collections of papers on specific topics. The aim is to build a community
of authors and readers to discuss the latest research and develop new ideas and research directions. Special Issues are led by
Guest Editors who are experts in the subject and oversee the editorial process for papers. Papers published in a Special Issue
will be collected together on a dedicated page of the journal website. For any inquiries related to a Special Issue, please
contact the Editorial Office.
