Diabetes management and treatment approaches outside of North America and West Europe in 2006 and 2015
(Springer, 2019-04-08)
Aims The impact of introducing new classes of glucose-lowering medication (GLM) on diabetes management remains unclear, especially outside North America and Western Europe. Therefore, we aimed to analyse trends in glycaemic ...
Imersões isométricas locais de superfícies pseudoesféricas e classes de equações diferenciais parciais
Baseado em [15, 16, 17], consideramos duas classes de equações diferenciais parciais que descrevem superfícies pseudoesféricas, a saber, a classe de equações evolutivas de ordem k ≥ 2, dada por [...] ,classificada por Chern ...
Fronsdal fields from gauge functions in Vasiliev's higher spin gravity
(2019)
In this paper, we revisit a number of issues in Vasiliev's theory related to gauge functions, ordering schemes, and the embedding of Fronsdal fields into master fields. First, we parametrize a broad equivalence class of ...
11D supergravity as a gauge theory for the M-algebra
(2004)
The eleven-dimensional gravitational action invariant under local Poincaré transformations is given by the dimensional continuation of the Euler class of ten dimensions. Here we show that the supersymmetric extension of ...
Transitionally commutative bundles and characteristic classes
(Medellín - Ciencias - Doctorado en Ciencias - MatemáticasEscuela de matemáticasUniversidad Nacional de Colombia - Sede Medellín, 2020-06-01)
Let p : E ! M be a principal G-bundle, over a manifold M. Assume that we can nd an open cover of M together with trivializations over them in such a way that the corresponding transition functions commute with each other ...
Gauge and integrable theories in loop spaces
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We propose an integral formulation of the equations of motion of a large class of field theories which leads in a quite natural and direct way to the construction of conservation laws. The approach is based on generalized ...
Elementos computacionales de la teoría de invariantes polinomiales de grupos finitos
(Universidad de los AndesMatemáticasFacultad de CienciasDepartamento de Matemáticas, 2021)
En este documento mostramos un procedimiento para calcular polinomios generadores del anillo de invariantes cuando nos es dada la acción de un grupo finito sobre un álgebra polinomial. El primer resultado presentado en ...
