Módulos irredutíveis para subálgebras de Heisenberg de álgebras de Krichever-Novikov / Representations of Heisenberg subalgebras of Krichever-Novikov algebras

Santos, Felipe Albino dos 20 February 2017 (has links)
Esta dissertação oferece uma introdução às já conhecidas álgebras de Krichever-Novikov se restringindo aos exemplos abordados previamente em Bremner (1995), Cox (2013), Cox e Jurisich (2013), Cox, Futorny e Martins (2014), Bueno, Cox e Furtony (2009), e as definições de estruturas que podem auxiliar a estudar estes espaços, incluindo álgebras de Lie afins, álgebras de loop e módulos de Verma. Considerando K uma álgebra de Krichever-Novikov do tipo 4-ponto, 3-ponto, elíptica ou DJKM e suas respectivas subálgebras de Heisenberg K\' = K hK , onde hK é a subálgebra de Cartan de K , nos Teoremas 3.2.3, 3.4.3, 3.6.3 e 3.8.3 são apresentados critérios explícitos de irredutibilidade para K\'-módulos do tipo -Verma. / This work gives an introduction to the already known Krichever-Novikov algebras limited only to the examples approached before in Bremner (1995), Cox (2013), Cox e Jurisich (2013), Cox, Futorny and Martins (2014), Bueno, Cox and Furtony (2009), and the structures definitions that could help us to study these spaces, including affine Lie algebras, loop algebras and Verma modules. Let K be a 4-point, 3-point, elliptic or DJKM Krichever-Novikov algebra and its respective Heisenberg subalgebras K\' = K hK , where hK is the K Cartan subalgebra. In the Theorems 3.2.3, 3.4.3, 3.6.3 and 3.8.3 we will give a explicit irreducibility criteria for -Verma K\'-modules.

Inverse Scattering For The Zero-Energy Novikov-Veselov Equation

Music, Michael 01 January 2016 (has links)
For certain initial data, we solve the Novikov-Veselov equation by the inverse scat- tering method. This is a (2+1)-dimensional completely integrable system that gen- eralizes the (1+1)-dimensional Korteweg-de-Vries equation. The method used is the inverse scattering method. To study the direct and inverse scattering maps, we prove existence and uniqueness properties of exponentially growing solutions of the two- dimensional Schrodinger equation. For conductivity-type potentials, this was done by Nachman in his work on the inverse conductivity problem. Our work expands the set of potentials for which the analysis holds, completes the study of the inverse scattering map, and show that the inverse scattering method yields global in time solutions to the Novikov-Veselov equation. This is the first proof that the inverse scattering method yields classical solutions to the Novikov-Veselov equation for the class of potentials considered here.

Teoria de Morse-Novikov e seus aspectos dinâmicos

Raphael, Lucas January 2018 (has links)
Orientadora: Profa. Dra. Mariana Rodrigues da Silveira / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Matemática , 2018. / A Teoria de Morse é baseada na obtenção de informações topológicas de uma variedade M diferenciável por meio de uma função real f : M !R com apenas pontos críticos não degenerados. Nesta dissertação estudamos uma adaptação desta teoria para funções com imagem no círculo S1. Este estudo é realizado considerando o recobrimento cíclico infinito de M induzido pelo recobrimento universal R sobre S1. Mostramos que, assim como no caso Morse, informações topológicas de M podem ser recuperadas através de um complexo de cadeias construído a partir dos pontos críticos de f . / Morse theory is based on recovering topological information about a smooth manifold M using a real valued function f : M ! R with a finite number of nondegenarate critical points. In this work we study an adaptation of this theory for circle valued maps. This study is done considering the infinite cyclic covering of M induced by the universal covering R of S1. We prove that, as in the Morse case, topological information of M can be recovered using a chain complex generated by the critical points of f .

Sur la topologie des sous-variétés lagrangiennes

Damian, Mihai 15 November 2010 (has links) (PDF)
Nous définissons deux nouvelles versions de l'homologie de Floer, l'homologie de Floer-Novikov et l'homologie de Floer relevée. Nous les appliquons pour obtenir de nouveaux résultats sur la conjecture d'Arnold concernant sous-variétés lagrangiennes exactes du fibré cotagent et sur la conjecture d'Audin qui porte sur le nombre de Maslov d'une sous-variété lagrangienne asphérique de l'espace euclidien.
