Numerical uniformization of hyperelliptic-m-symmetric riemann surfaces
No full textIn this note we consider hyperelliptic-M-symmetric Riemann surfaces, that is, hyperelliptic Riemann surfaces with a symmetry with maximal number of components of fixed points. These surfaces can be represented either by real algebraic curves or by real Schottky groups. To obtain one of these in terms of the other is difficult. In this note we proceed to describe explicit transcendental relations between the different sets of parameters these representations give. This can be used to obtain a computer program which permits obtain numerical approximations of the algebraic curve in terms of real Schottky group and viceversa
An asymptotic formula for the number of eigenvalues of a differential operator
No full textIn this work, it is proved that the spectrum of an differential operator with unbounded operator coefficients in elliptic type with partial derivatives is pure discrete and an asymptotic formula is found for the number of eigenvalues of this operator
Jordan nilalgebras of dimension 6
No full textIt is known the classification of commutative power-associative nilalgebras of dimension ? 4 (see, [4]). In [2], we give a description of commutative power-associative nilalgebras of dimension 5. In this work we describe Jordan nilalgebras of dimension 6
A note on asymptotic smoothness of the extensions of Zadeh
No full textThe concept of asymptotic smooth transformation was introduced by J. Hale [10]. It is a very important property for a transformation between complete metric spaces to have a global attractor. This property has also consequences on asymptotic stability of attractors. In our work we study the conditions under which the Zadeh’s extension of a continuous map f : R??R? is asymptotically smooth in the complete metric space F(R?) of normal fuzzy sets with the induced Hausdorff metric d?(see Kloeden and Diamond [8])
Dibaric algebras
No full textHere we give basic properties of dibaric algebras which are motivated by genetic models. Dibaric algebras are not associative and they have a non trivial homomorphism onto the sex differentiation algebra. We define first join of dibaric algebras next indecomposable dibaric algebras. Finally, we prove the uniqueness of the decomposition of a dibaric algebra, with semiprincipal idempotent, as the join of indecomposable dibaric algebras
Nonexistence of nontrivial solutions for an asymmetric problem with weights
No full textIn this paper we establish a nonexistence result for an elliptic problem involving the one-dimentional p-Laplacian operator with asymmetric second member of the equation
La Movilidad del Cuerpo en la Configuración del Espacio de Trabajo Artesanal. Extracto de Seminario UCN
Get PDFEl estudio se desarrolla analizando dialécticamente la cualidad propia del hombre, la movilidad. Esta característica lo diferencia de la máquina en forma radical.Utilizando esta propiedad humana, se plantea su análisis arquitectónico en los espacios laborales, para poder de este modo dar una significación al hombre, valorando su importancia en el quehacer productivo
