Resumo: | In this work, we establish a new method to calculate the index of curves in a neighborhood of a boundary and we show that the index of a trajectory of a vector field which intersects the boundary at two points is 1/2. Using this method we extended the index definition for discontinuous vector fields with a regular transition manifold and we calculate the index for closed curves that intersect the variety of transition = f−1(0), where f is a differentiable function, and is the union of the regions tangency, sewing, sliding and escaping. We also show that the index for solutions of the discontinuous vector field that are −closed of type 1 and intersect the boundary at 2-point is equal to 1. We also establish an index theory for discontinuous vector fields when the transition manifold is not regular in a point and we show that the index is given by the calculation in its regular regions and add ±1/2, depending on the dynamics at the non-regular point. We apply the theory of index developed in this work and we give quotas for the indices of continuous vector field and for polynomial vector fields on two zones. Finally, we demonstrate a version of the Poincaré-Hopf Theorem for discontinuous vector fields in compact manifolds. |

Utilizando este método estendemos a definição do índice para campos vetoriais descontínuos com variedade de transição regular e calculamos o índice para curvas fechadas que intersectam a variedade de transição = f−1(0), onde f é uma função diferenciável, e é a união das regiões de tangência, de deslize, escape ou costura. Mostramos também que o índice para soluções do campo vetorial descontínuo que são −fechadas do tipo 1 e intersectam o bordo em 2 pontos é igual a 1. Estabelecemos também uma teoria do índice para campos vetoriais descontínuos quando a variedade de transição não é regular em um ponto e mostramos que o índice é dado pelo cálculo em suas regiões regulares e somar ±1 2 , a depender da dinâmica no ponto não regular. Aplicamos a teoria do índice desenvolvida neste trabalho e damos cotas para índices de campos vetoriais contínuos e para campos vetoriais polinomiais por partes. Finalmente, demostramos uma versão do Teorema de Poincaré-Hopf para campos vetoriais descontínuos em variedades compactas.Submitted by Franciele Moreira (francielemoreyra@gmail.com) on 2017-12-27T12:48:10Z No. of bitstreams: 2 Tese - Pablo Vandré Jacob Furlan - 2017.pdf: 3620430 bytes, checksum: 7275b5a734d392f78e2829268555ec68 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-12-28T09:41:38Z (GMT) No. of bitstreams: 2 Tese - Pablo Vandré Jacob Furlan - 2017.pdf: 3620430 bytes, checksum: 7275b5a734d392f78e2829268555ec68 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-12-28T09:41:38Z (GMT).

In this work, we establish a new method to calculate the index of curves in a neighborhood of a boundary and we show that the index of a trajectory of a vector field which intersects the boundary at two points is 1/2. Using this method we extended the index definition for discontinuous vector fields with a regular transition manifold and we calculate the index for closed curves that intersect the variety of transition = f−1(0), where f is a differentiable function, and is the union of the regions tangency, sewing, sliding and escaping. We also show that the index for solutions of the discontinuous vector field that are −closed of type 1 and intersect the boundary at 2-point is equal to 1. We also establish an index theory for discontinuous vector fields when the transition manifold is not regular in a point and we show that the index is given by the calculation in its regular regions and add ±1/2, depending on the dynamics at the non-regular point. We apply the theory of index developed in this work and we give quotas for the indices of continuous vector field and for polynomial vector fields on two zones.
