ExistÃncia de moduli para equivalÃncia HÃlder de funÃÃes analÃticas / Moduli existence for HÃlder equivalence of analytical functions

Joserlan Perote da Silva 27 April 2016 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Neste trabalho, mostramos que equivalÃncia HÃlder de germes de funÃÃes analÃticas (C2, 0) → (C, 0) admite moduli contÃnuo. Mais precisamente, construimos um invariante da equivalÃncia HÃlder de tais germes que varia continuamente numa famÃlia ft : (C2, 0) → (C, 0). Para um Ãnico germe ft o invariante de ft à dado em termos dos coeficientes principais das expansÃes assintÃticas de ft ao longo dos ramos da curva polar genÃrica de ft. / In this work, we show that HÃlder equivalence of analytic functions germs (C2, 0) → (C, 0)admits continuous moduli. More precisely, we constructed an invariant of the HÃlder equivalence of such germs that varies continuously in a family ft : (C2, 0) → (C, 0). For a single germ ft the invariant of ft is given in terms of the leading coefficients of the asymptotic expansion of ft along the branches of generic polar curve of ft .
