Mathematical Theory of Capillarity

Description

The modern theory of capillarity originated in achievements of Laplace in 1806, based on insights introduced by Thomas Young in 1805. There followed a single definitive work of Gauss in 1830, and then an interlude of well over a century, during which the topic received little attention. In contemporary times, the demands of space exploration and also of medicine, of biology and of industrial procedures have been inspiring new developments of varying character. These have been appearing in frequently uncoordinated ways and often in ignorance of related developments from other sources. We note recent announcements of active interest, appearing in journals as disparate in their structures and goals as the J. Am. Chem. Soc., Physics of Fluids, and J. reine angew. Math. Much is now happening, independent new insights are emerging, and a new and broader theory will certainly ensue. The venue of this conference can be expected to be instrumental in that development and to offer opportunities for cooperation among investigators with varying backgrounds and points of view. To that effect we intend to invite explicitly to this Workshop major contributors from all fields, who are known to us. We emphasize additionally that we welcome unaccustomed insights, and we thus encourage others who may wish to speak to send summaries of the material to rfinn@stanford.edu for consideration, based on its perceived relevance and interest for the topic.

Description

Modeling physical systems using PDEs has been the object of science for centuries and has taken a multitude of forms over time. In many situations, one fundamental aspect of this process is to identify and isolate the system of interest from a possible environment. Mathematically, this translates into boundary-value or initial-boundary value problems for nonlinear PDEs whereby the boundary conditions encode the connection between the system and the "rest of the world". A big challenge is to find boundary conditions that are both physically relevant (modeling) and mathematically appropriate (well-posedness problems). This old theme is being actively revived directly or indirectly by several developments that shape the next step of Mathematical Physics: out-of-equilibrium systems, where one can drive a system out of equilibrium by external forcing; PDEs on graphs as models of complex systems, where one can describe evolutionary processes on graphs with certain boundary conditions at the vertices. Integrable and exactly solvable systems are known to play an important role in establishing a better understanding of fundamental issues in Mathematical Physics and these new developments are no exception. This workshop will aim at bringing together some of the latest developments in those areas and related methods.

Description

Expectations from modern medicine are very high and this makes this field very demanding as far as the questions posed and the needed solutions are concerned, related to early diagnosis, effective therapy, accurate intervention, real time monitoring, procedures/systems/instruments optimization, error reduction and knowledge extraction. In parallel, following the explosive production of biological data concerning DNA, RNA and protein biomolecules, a plethora of questions has been raised regarding their structure, their function, the interactions between them, their relationships and their dependencies, their regulation and expression, their location and their thermodynamic characteristics. Furthermore, the interplay between medicine and biology leads to fields like molecular medicine and systems biology which are further interconnected with physics, mathematics, informatics and engineering creating new islands in the ocean of scientific interconnections like medical physics and biophysics, medical informatics, bioinformatics and computational biology, nanobiotechnology and astrobiology. We hope that this workshop will host exciting questions and intelligent algorithmic solutions in these interdisciplinary fields of medicine and biology bringing together scientists from different research fields into a creative and fertile scientific knowledge interchange.


Modeling in Ecology, Economics and Social Sciences

Dimitrios Thomakos1

1University of Peloponnese, Department of Economics, Greece

Description

Owing to masses of digital real-world data it is now possible to create and validate models of human behaviour. Of special interest are human activities connected to use of Internet - their habits, movements or likings. Simple models, basing on fundamental physical laws and phenomena can be of instant use in this case. The Workshop is also open to new techniques connected to data mining and statistics that can facilitate the process of models' input preparation as well as help to discover new non-trivial phenomena.

The session will focus on recent advances in the field and will include both theoretical and applied research in complex systems. Particular emphasis will be given to the interdisciplinary nature of complex networks. A wide range of topics will be covered, such as network structure and dynamics on networks, coupled networks, spreading, synchronization, visualization, algorithms, large-scale data analysis, as well as networks of interest to biology, sociology, computer science, economics, medicine, linguistics, etc.


Geometric integration in physical sciences and engineering

Dimitrios Vlachos1

1University of Peloponnese, Department of Informatics and Telecommunications, Greece

Description

Many differential equations, which are of interest in the physical sciences and engineering, exhibit geometric properties that are preserved by the dynamics. Discrete Lagrangian integrators, as a special type of geometric integration, has been recent interest in developing numerical schemes that preserve as many of these geometric invariants as possible. Such methods are of particular interest for problems that can be described by geometric mechanics, wherein the preservation of physical invariants such as the energy, momentum, and symplectic form can be important when simulating long-time dynamics of such systems. The aim of the session is to bring together researchers in mathematics, computer science, physical sciences, and engineering, who are interested in the broad area of numerical methods (for ordinary differential equations to partial differential equations) that preserve the underlying structure of the governing differential equations.
