Announcements

On Wednesday, 5 April 2023, MDPI and the journal Symmetry (ISSN: 2073-8994) organized a webinar on symmetry, titled “Nonlinear Analysis and Its Applications in Symmetry II”. The webinar focused on nonlinear analysis and its applications.

This webinar was devoted to recent advances in nonlinear analysis and its applications. It consisted of two talks. In the first talk delivered by Dr. Alexander Ramm, the speaker presented his recent results on Navier–Stokes equations. In the second talk by Prof. Dr. Alexander J. Zaslavski, a feasibility problem with infinite sets in a metric space was discussed. The speaker presented a new algorithm for this problem and analyzed its convergence.

Please note that this webinar is associated with a Special Issue in Symmetry, titled “Fixed Point Theory and Its Applications Dedicated to the Memory of Professor William Arthur Kirk”. The deadline for submissions is 30 September 2023.

Webinar Chair and Keynote Speaker:

• Dr. Alexander Zaslavski, Department of Mathematics, The Technion, Israel Institute of Technology, Israel
• Prof. Dr. Alexander G. Ramm, Department of Mathematics, Kansas State University, Manhattan, KS 66506, USA

As a leading open access publisher, MDPI provides scholars with a high-quality and rich academic exchange platform by continuously expanding into new and exciting research areas.

In December 2022, MDPI launched five new journals, covering multiple subjects such as life sciences, biology, medicine and pharmacology, social sciences and humanities. These new journals are being edited by established scholars across the world.

If you are interested in creating more open access journals with us to publish cutting-edge research, please send your journal proposal application to newjournal-committee@mdpi.com.

MDPI is pleased to announce that we now display the co-authors’ email addresses in addition to the corresponding author’s email address on the webpage of published papers, protected by Captcha. For more information about this change, please visit the journal’s instructions for authors page. 

We believe this change will facilitate academic discussions and advance our cause of open science and research. The corresponding authors are responsible for communicating with their co-authors and indicating in our system (https://susy.mdpi.com/) if co-authors would prefer for their email addresses not to be displayed.
