Previous issue date: 2013-09-20 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / In this work we study surfaces M in hyperbolic space whose mean curvature H and
Gaussian curvature KI satisfy the relation 2(H 􀀀1)e2μ +KI(1􀀀e2μ) = 0; where μ is a
harmonic function with respect to the quadratic form s = 􀀀KII + 2(H 􀀀 1)II; and I,
II denote, respectively, the first and second quadratic form of M. These surfaces are
called Generalized Weingarten surfaces of harmonic type (HGW-surfaces). We obtain
a representation type Weierstrass for these surfaces that depend on three holomorphic
functions. As an application we obtain a representation type Weierstrass for Bryant
surfaces and classify all HGW-surfaces of rotation. / Neste trabalho estudamos superfícies M no espaço hiperbólico cuja curvatura média H e a
curvatura Gaussiana KI satisfazem a relação 2(H􀀀1)e2μ+KI(1􀀀e2μ) = 0; onde μ é uma
função harmônica com respeito a forma quadrática s = 􀀀KII +2(H 􀀀1)II; onde I e II
são respectivamente a primeira e segunda forma quadrática de M. Estas superfícies serão
chamadas de Superfícies Weingarten generalizada tipo harmônico (Superfícies-WGH).
Obtemos uma representação tipo Weierstrass para estas superfícies que dependem de três
funções holomorfas. Como aplicação obtemos uma representação tipo Weierstrass para
superfícies de Bryant e classificamos as superfícies-WGH de rotação.
