Nous determinons toutes les valeurs de N telles que X0(N) est bielliptique. D'autre part, nous r'esolvons la question arithm'etique de trouver toutes les valeurs de N pour lesquelles X0(N) a un nombre infini de points ...
El esquema de trabajo del que nos hemos valido trata de abarcar desde el arraigo de la doctrina anarquista en las localidades del Bajo Aragón, y fundamentalmente en Mas de las Matas, desde una tradición, una cultura y ...

La pèrdua de protagonisme del treball com a eix vertebrador de les persones en les societats postindustrials i la comercialització de la vida social en quant consum d'estils de vida en les societats occidentals, ens fa ...

The filling length of an edge-circuit η in the Cayley 2-complex of a finite presentation of a group is the minimal integer length L such that there is a combinatorial null-homotopy of η down to a base point through loops ...
In this paper we consider the properties of moduli of smoothness of fractional order. The main result of the paper describes the equivalence of the modulus of smoothness and a function from some class.
We review several results concerning the long time asymptotics of nonlinear diffusion models based on entropy and mass transport methods. Semidiscretization of these nonlinear diffusion models are proposed and their numerical ...
Consider a Riemannian manifold equipped with an infinitesimal isometry. For this setup, a unified treatment is provided, solely in the language of Riemannian geometry, of techniques in reduction, linearization, and stability ...

R.P. Boas has found necessary and sufficient conditions of belonging of function to Lipschitz class. From his findings it turned out, that the conditions on sine and cosine coefficients for belonging of function to Lip α(0 ...

We are interested in coupled microscopic/macroscopic models describing the evolution of particles dispersed in a fluid. The system consists in a Vlasov-Fokker-Planck equation to describe the microscopic motion of the ...
It is known that, in a locally presentable category, localization exists with respect to every set of morphisms, while the statement that localization with respect to every (possibly proper) class of morphisms exists in ...
We prove that any subanalytic locally Lipschitz function has the Sard property. Such functions are typically nonsmooth and their lack of regularity necessitates the choice of some generalized notion of gradient and of ...

Using the continuation method we prove that the circular and the elliptic symmetric periodic orbits of the planar rotating Kepler problem can be continued into periodic orbits of the planar collision restricted 3-body ...
