Existence of strong solutions in a larger space for the shallow-water system
, 2013
"... This paper is dedicated to the study of both viscous compressible barotropic fluids and Navier-Stokes equation with dependant density, when the viscosity coefficients are variable, in dimension d ≥ 2. We aim at proving the local and global well-posedness for respectively large and small initial data ..."

Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

It is shaped and moved by information turbulences of various origins, processed and transmitted almost instantly by tele-communicated, information systems, in the absence of the institutional regulation of global capital ows
Existence and Uniqueness for Shape From Shading Around Critical Points: Theory and an Algorithm
"... To approach the difficult question of existence and unique-ness of solutions for the shape-from-shading problem, we have examined the image irradiance equation using notation and concepts from dynamic systems theory. The method of charac-teristic strips used by Horn (1975) defines a dynamic system o ..."

by the image dynamic system. The stable and unstable man-ifolds associated with certain critical points in the image determine locally unique solution surfaces. A theorem about unstable manifolds (the Lambda Lemma) suggests a class of computational methods for finding stable and unstable mani-folds around
Smarandache ν−Connected spaces
"... Abstract In this paper Smarandache ν−connectedness and Smarandache locally ν−connectedness in topological space are introduced, obtained some of its basic properties and interrelations are verified with other types of connectedness. ..."

ABSTRACT Title of dissertation: Weakly Compressible Navier-Stokes Approximation of Gas Dynamics
"... This dissertation addresses mathematical issues regarding weakly compressible approximations of gas dynamics that arise both in fluid dynamical and in kinetic settings. These approximations are derived in regimes in which (1) transport coeffi-cients (viscosity and thermal conductivity) are small and ..."

while Re maintains order unity, we derive the weakly com-pressible Navier-Stokes approximation—a quadratic system. Each of these weakly compressible approximations govern both the acoustic and the incompressible modes of the gas. In the fluid dynamical setting, our derivations begin with the fully
On the regularity of the bilinear term for solutions to the incompressible Navier-Stokes equations
"... We derive various estimates for strong solutions to the NavierStokes equations in C([0, T ), L 3 (R 3 )) that allow us to prove some regularity results on the kinematic bilinear term. Introduction and definitions The Cauchy problem for the Navier-Stokes equations governing the time evolution of ..."

Pseudogap and Kinetic Pairing Under Critical Differentiation of Electrons in
, 2000
"... Superconducting mechanism of cuprates is discussed in the light of the proximity of the Mott insulator. The proximity accompanied by suppression of coherence takes place in an inhomogeneous way in the momentum space in finite-dimensional systems. Studies on instabilities of metals consisted of such ..."

of such differentiated electrons in the momentum space are reviewed from a general point of view. A typical example of the differentiation is found in the flattening of the quasiparticle dispersion discovered around momenta (π,0) and (0,π) on 2D square lattices. This flattening even controls the criticality of the metal
1Capacity Theorems for the Fading Interference Channel with a Relay and Feedback Links
"... Abstract—Handling interference is one of the main challenges in the design of wireless networks. One of the key approaches to interference management is node cooperation, which can be classified into two main types: relaying and feedback. In this work we consider simultane-ous application of both co ..."
