Symmetry recognition in group-theoretic computational schemes for complex structural systems

A Zingoni - Computers & structures, 2012 - Elsevier
Group theory provides a formal means for exploiting symmetry in the analysis of physical
systems. In current group-theoretic formulations, it is assumed that the symmetry properties …

A group-theoretic finite-difference formulation for plate eigenvalue problems

A Zingoni - Computers & structures, 2012 - Elsevier
We consider the problem of the free vibration of plates, and develop an efficient group-
theoretic formulation for the solution of the problem by the method of finite differences. The …

Multiple Positive Symmetric Solutions to p‐Laplacian Dynamic Equations on Time Scales

YH Su, CY Huang - Discrete Dynamics in Nature and Society, 2009 - Wiley Online Library
This paper makes a study on the existence of positive solution to p‐Laplacian dynamic
