Special Issue Information

Dear Colleagues,

The mathematical theory of “rigidity” investigates the rigidity and flexibility of structures which are defined by geometric constraints (fixed lengths, fixed areas, fixed directions, etc.) on a set of rigid objects (points, lines, polygons, etc.). This theory has both combinatorial and geometric aspects and draws on techniques from a wide range of mathematical areas, including graph theory, matroid theory, positive semidefinite programming, representation theory of symmetry groups, algebraic and projective geometry, and even operator theory.
Since the rigidity and flexibility properties of a structure—either man-made, such as a building, bridge or mechanical linkage, or found in nature, such as a biomolecule, protein or crystal—are critical to its form, behavior and functioning, rigidity theory has many practical applications in fields such as engineering, robotics, computer-aided design, materials science, medicine and biochemistry.
Since symmetry appears widely in both natural and man-made structures, the study of structures with additional symmetry—both finite structures with point group symmetry and infinite structures with periodic or crystallographic symmetry—is an important area of research which has seen a dramatic increase in interest over the last few years, both in mathematics and in the applied sciences.
The aim of this special issue of “Symmetry” is to present a broad spectrum of the latest developments and current research concerning the rigidity and flexibility of symmetric geometric constraint systems, and to foster the exchange of ideas among workers who focus on different aspects and applications of the field.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly 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 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Abstract:
The eigenmode analysis was employed to investigate the rigidity of various networks determined by certain conditions on zero frequency modes. We introduced the analysis to identify structural characterization of two-dimensional regular networks and also irregular networks. The analysis was shown reliable to determine the global network rigidity, and can also identify local floppy regions in the mixture of rigid and floppy regions. It is useful to determine the structural characteristics of general networks which the traditional Maxwell counting scheme based on the statistics of nodes (degrees of freedom) and bonds (constraints) cannot usually determine. The eigenmode analysis is under development for various practical applications on more general network structures in three dimensions.
