El anillo de Witt y sus módulos
(Universidad Michoacana de San Nicolás de Hidalgo, 2021-03)
Our objective is to define the structure of Witt Rings and their modules NK*(A) defined from nilpotent endomorphisms. We will start by defining Binomial rings in order to understand a little of the behavior of some Witt ...
O anel dos vetores de Witt e o problema de Waring
(2011-02-02)
Neste trabalho, fazemos um estudo geral do anel de valorização discreta completo. Construímos o anel dos vetores deWitt, denotado por W(A), com coeficientes em um anel comutativo com unidade A. Definimos W(k), onde k é um ...
Infinite dimensional Lie algebra associated with conformal transformations of the two-point velocity correlation tensor from isotropic turbulence
(Birkhauser VerlagBasel, 2013)
We deal with homogeneous isotropic turbulence and use the two-point velocity correlation tensor field (parametrized
by the time variable t) of the velocity fluctuations to equip an affine space K3 of the correlation vectors ...
Grupos Nil de Bass de Z[C p 2 ] y para Z[C p × C p ]
(Universidad Michoacana de San Nicolás de Hidalgo. Universidad Nacional Autónoma de México, 2011-02)
In the present work of thesis we set out to study the so-called Nil-groups of Bass of the rings of group Z [C p 2] and Z [C p × C p]. The definition of the Bass Nil-groups is given by considering a ring R and seeking to ...

Ensayo de clonación de la proteína dihidropirimidina deshidrogenasa (DHPD) de papa en el vector pGBKT7
(Universidad de los AndesMicrobiologíaFacultad de CienciasDepartamento de Ciencias Biológicas, 2022-07-25)
La proteína dihidropirimidina deshidrogenasa (DHPD) es la primera enzima involucrada en la ruta del catabolismo de pirimidinas. Se ha observado que la DHPD se sobreexpresa en plantas de Oryza sativa (arroz) sometidas a ...
