主 题:Harmonic form orthogonal decomposition Diriehlet norm
摘 要:It is considered the class of Riemann surfaces with dimT1=0, where T1 is a subclass of exactharmonic forms which is one of the factors in the orthogonal decomposition of the space Ω^H of harmonic forms of the surface, namely Ω^H=*Ω^H+T1+*T0^H+T0^H+T2 The surfaces in the class OHD and the clase of planar surfaces satisfy dimT1 =0. *** posed the question whether there might exist other surfaces outside those two classes. Here it is shown that in the case of finite genus g, we should look for a surface S with dimTl = 0 among the surfaces of the form Sg/K , where Sg is a closed surface of genus g and K a compact set of positive harmonic measure with perfect components and very irregular boundary.
