Dear Colleagues,

As a chemist, I have been trying very hard to set up an axiomatic formula of symmetry, order, entropy and stability. The task is truly very big and my efforts stirred up more problems than it appeared to have solved. This is the main reason that I am motivated to launch the journals Entropy (http://www.mdpi.com/journal/entropy/), Symmetry (http://www.mdpi.com/journal/symmetry/) together with several scientists, see the editorials at http://www.mdpi.com/1099-4300/1/1/1/pdf/ and http://www.mdpi.com/2073-8994/1/1/1/pdf/. I sincerely welcome you to contribute your paper and bring some progress to the studies of this topic.

Title: Symmetry, Symmetry Breaking and Topology
Author: Siddhartha Sen Email: sen@maths.ucd.ie
Abstract: Symmetry is a feature used to describe the ground state property of many systems: from crystals to the vacuum state of grand unified theories. The symmetry of a system is desribed by group theory. The ground state of the system is invariant under a group G. A standard problem that arises is that this symmetry can change as the external parameters of the system are modified.The ground state symmetry changes from G to a subgroup og G. Such "phase transistions"have been extensively studied within the framework of an approach due to Landau. Recently there has been interest in looking at phase transitions that do not fit into the standard Landau picture. These are "toplogical phase transitions". In this review we first outline the approach of Landau from a slightly different perspective.. We use group theory and topological arguments to determine might restrict transitions from G to its subfgroups ie certain subgroups are not allowed as symmetries of the ground state. We describe two applications of this approach, one for finite symmetry groups and one for continous symmetry and include a brief summery of toplogical ideas we need. We then turn to a description of "toplogical phases" and outline a possible example of such a transition. Here the ground state has toplogical features and cannot be described simply in terms of symmetry groups.

Title: Symmetries in Fluid Solid Interaction
Author: Ashwin Vaidya; E-mail: vaidyaa@mail.montclair.edu
Abstract: The subject of particle sedimentation in fluids is a gold mine to look for pattern selection problems. The steady and unsteady behavior of the particle interactions with fluids display some very interesting dynamics. If the fluid happens to be a non-Newtonian fluid the physics becomes even more complex and interesting. In this paper we will examine the symmetry issues that arise in some of these problems and investigate their mechanisms from a mechanical and also thermodynamic perspective.

Title: Classifying Measures of Entropy
Author: Angel Garrido
Affiliation: Departamento de Matemáticas Fundamentales, Facultad de Ciencias de la UNED, Paseo Senda del Rey 9. 28040-Madrid, Spain; E-Mail: agarrido@mat.uned.es
Abstract: Our paper analyzes some aspects of Uncertainty Measures. We need to obtain new ways to model adequate conditions or restrictions, constructed from vague pieces of information. The more classical entropy measure proceeds from some scientific fields; concretely, from Statistical Physics and Thermodynamics. With the time it was adapted by Claude Shannon, so creating the Information Theory. But Alfred Rényi shows that there exist different and valid entropy measures, according the purpose and/or the need of application. So, it will be very necessary to classify the different types of measures, and shown their mutual relationships. For these reasons, we attempt to obtain here an adequate classification of such fuzzy entropy measures.
