Special Issue Information
Dear colleagues,
Lie theory, symmetry analysis, conservation law, and variational principle are useful mathematical tools for various nonlinear differential equations, and their extensions for non-differential problems have increasingly become more promising.
This Special Issue focuses itself on fractal differential equations for various discontinuous problems using the two-scale fractal theory and two-scale mathematics.
The two-scale method considers the same problem by using two different scales—the larger scale always leads to a differential model by the continuum mechanics, while the smaller scale can figure out the discontinuous property of the same problem. For example, water is continuous on a micro scale, and all laws in fluid mechanics can be used to describe its motion. However, when we measure the motion on a molecule’s scale, many uncertainty phenomena arising in the macro observation can be solved certainly.
This Special Issue welcomes the following main topics:
1) Two-scale fractal theory for discontinuous problems;
2) Two-scale fractal calculus for discontinuous problems;
3) Conservation laws for fractal differential equations;
4) Symmetry analysis of fractal differential equations;
5) Variational principles for fractal differential equations;
6) Lie theory for fractal differential equations;
7) Other methods for fractal differential equations.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
Benefits of Publishing in a Special Issue
