Entropy 2021 has been a success!

We would like to thank our chair, organizers, speakers, sponsors, and all the attendees for making this a great meeting.

See you at the next edition!

Welcome from the Chair

The concept of entropy emerges initially from the scope of physics, but it is now clear that entropy is deeply related to information theory and the process of inference. Today, entropic techniques have found a broad spectrum of applications in all branches of science.

The conference will be organized into six sessions, which reflect the inter-disciplinary nature of entropy and its applications:

  • Statistical Physics
  • Information Theory, Probability and Statistics
  • Thermodynamics
  • Quantum Information and Foundations
  • Complex Systems
  • Entropy in Multidisciplinary Applications

    The inter-disciplinary and multi-disciplinary nature of contributions from both theoretical and applied perspectives are welcome, including papers addressing conceptual and methodological developments, as well as new applications of entropy and information theory.

    All accepted abstracts will be published in the proceedings of the conference. Moreover, participants are cordially invited to contribute with a full manuscript to Entropy Special Issue "Entropy: The Scientific Tool of the 21st Century".

    Special Issue Submission deadline: 30 June 2021
    Papers presented at the conference will be granted a 200 CHF discount!

    The conference is sponsored by MDPI, the publisher of the open-access journal Entropy and follows the very successful meeting Entropy 2018: From Physics to Information Sciences and Geometry held in May 2018 in Barcelona, Spain.

    We very much look forward to your participation.

    The registration fee for Oral Presentation participants is €100 per participant, and the fee for Poster Presentation (just shown in a slide show & as a downloadable single slide) participants is €50 per participant. Those attending without any submissions will be charged €25 per participant; this is an optional fee, but is necessary if you wish to join live sessions during Entropy 2021. The authors (Invited speakers, Oral Presentation, Poster Presentation) will not pay an extra fee for the live sessions.

    Finally, only registered authors will be able to apply for the Conference Awards, and the 200 CHF discount on the publication fees for the special issue "Entropy: The Scientific Tool of the 21st Century", in the journal Entropy.

    Participation to the conference is considered final only once the registration fee has been paid. Registration by at least one author per paper, denoted as Covering Author, is required to cover participation and publication of any submission. Covering Author registration deadline is 7 April 2021. Your abstract and submission will be withdrawn if you do not complete the registration by this date.

    Authors with multiple contributions: Please note that one author registration will cover 3 accepted contributions at most.

    When registering, please provide us with your institutional email address. This will accelerate the registration process. If you are registering several people under the same registration, please do not use the same email address for each person, but their individual institutional email addresses. Please note that, submission and registration are two different processes. During registration, if possible, use the same email address you used to submit your abstract(s). Otherwise, leave us a comment in the registration form, providing the email address used during the submission process.

    Certificate of Attendance: Upon request, the participants of the event will receive an electronic Certificate of Attendance by email once the event is concluded.

    Payment methods

    Credit card

    Instructions for Authors

    Generic information

    The Entropy 2021: The Scientific Tool of the 21st Century will accept:

    1. An abstract (150–300 words) in English
    2. If the abstract is accepted for this conference, the author will be invited to submit a poster presentation or video presentation before 21 April 2021. Please upload the Poster PDF in the field "Presentation PDF (optional)", the video in the field "Presentation video (mp4 / webm / ogg - max 250Mb) (optional)" and PPT in the field "Presentation PPT (optional)". Please also upload a copy of the accepted abstract as word in the field "Original files".
    3. About Oral presentation:
      The slot for Oral presentation is 15 min. We would advise to prepare your presentation to a maximum of 10-12 min to leave at least 3 min for Q&A. The video of your presentation should be saved in mp4 format – this will be used in case of bad connection.

    4. About Poster presentation:

      We would recommend to:

      (1) prepare one single Poster that should be A0 size, vertical – it can then be made available as a PDF printable document. There are no restrictions / template available. Thus, authors can choose the font type and size that better shows your research. We would also recommend to include a header – about 15 cm height with logos (corresponding to the Conference name, Title of the poster and Authors’ names, and your affiliation(s).

      (2) prepare 2 or 3 slides that can be commented by you and saved as a video presentation or a short video – mp4 format. Anyway, this must not exceed 2-3 min to play.
