Modelo que identifica el nivel de madurez de los procesos de las pequeñas empresas del sector industrial
(2007)
La alta competitividad existente en los mercados objetivo y las pautas que marca la globalización ensombrecen el futuro de las pequeñas empresas en México, lo cual se magnifica debido a que las capacidades de respuesta de ...
Operator equalities for singular integral operators and their applications
(2005)
The article consists of tow parts. In the first, we stablish a relation between the singular integral operators on the unit circle with a model orientation reversing shith operator and the singular integral operators on ...
Modelos cíclicos y modelos abiertos de sistemas con recursos recuperables
(2005)
Se plantean problemas para modelos cíclicos y abiertos de sistemas con recursos recuperables con base en la aplicación del aparato matemático de las ecuaciones funcionales con desplazamientos.
Eigenvalues, K-theory and Minimal Flows
(2007)
Let (Y, T) be a minimal suspension flow built over a dynamical system (X, S) and with (strictly positive, continuous) ceiling function f : X ! R. We show that the eigenvalues of (Y, T) are contained in the range of a trace ...
CONTINUOUS AND DISCRETE FLOWS ON OPERATOR ALGEBRAS
(2009)
Let (N, R, ) be a centrally ergodic W* dynamical system. When N is not a factor, we show that, for each t 6= 0, the crossed product induced by the time t automorphism t is not a factor if and only if there exist a rational ...
THE C*-ALGEBRAS ASSOCIATED TO TIME-t AUTOMORPHISMS OF MAPPING TORI
(2006)
We find the range of a trace on the K0 group of a crossed product by a time-t automorphism of a mapping torus. We also find a formula to compute the Voiculescu-Brown entropy for such an automorphism. By specializing to the ...
TEACHERS' CONSTRUCTION OF DYNAMIC MATHEMATICAL MODELS BASED ON THE USE OF COMPUTATIONAL TOOLS
(2009)
To what extent does the use of computational tools offer teachers the possibility of constructing dynamic models to identify and explore diverse mathematical relations? What ways of reasoning or thinking about the problems ...
