Existence and uniqueness for some two-scale systems involving tangential operators
No full textWe will present some existence and uniqueness theorems for two different two-scale problems ([1]). In this framework, a two-scale problem is a system of PDEs involving two unknowns (u; u_1), the first one just depending on a set of space variables denoted by x (usually called the macroscopic or slow variables) and on the time t, the second one depending on a second set of spatial variables y, beside the old ones (i.e. u_1 depends on (x; y; t)). The second set of space variables y are usually called microscopic or fast variables. Such kind of problems have a wide range of applications in many models in which physical properties at a macroscopic level are affected by phenomena taking place at a microscopic level and which, in turn, are affected by the evolution of the macroscopic state variable. A relevant applications of these kind of problems takes place in the wellknown

A notion of total variation depending on a metric with discontinuous coefficients
No full textGiven a function u : OMEGA subset-or-equal-to --> R, we introduce a notion of total variation of u depending on a possibly discontinuous Finsler metric. We prove some integral representation results for this total variation, and we study the connections with the theory of relaxation
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A Nonconvex Variational Problem With Constraints
No full textA multidimensional version of Liapunov-type theorems is proven. As an application, it is proven that, under proper hypothesis on the possibly nonconvex function f, the problem min integral(0)(T) f(u'(t)) dt on the subset of W-1,W-p([0,T],R(n)) Of those functions u satisfying the prescribed boundary conditions and whose trajectory lies out of a prescribed open subset of R(n) admits at least one solution
Existence, uniqueness and concentration for a system of PDEs involving the Laplace-Beltrami operator
No full textIn this paper we derive a model for heat diffusion in a composite medium in which the different components are separated by thermally active interfaces. The previous result is obtained via a concentrated capacity procedure and leads to a non-stantard system of PDEs involving a Laplace-Beltrami operator acting on the interface. For such a system well-posedness is proved using contraction mapping and abstract parabolic problems theory. Finally, the exponential convergence (in time) of the solutions of our system to a steady state is proved
