Geometry and Spectra of Compact Riemann Surfaces

This vintage monograph is a self-contained creation to the geometry of Riemann surfaces of continuing curvature –1 and their size and eigenvalue spectra. It specializes in topics: the geometric thought of compact Riemann surfaces of genus more than one, and the connection of the Laplace operator with the geometry of such surfaces.

By the definition of α0 , N1,ε and the smoothness of α → µα there holds µε2 ωk < −2ε 1−γ 2 for k ≤ N1,ε . 10 implies µk,ε < −ε 1−γ 2 for k ≤ N1,ε and ε → 0. Consider the following subspace M1 ⊆ HΣε M1 = span {φk (εy1 )uk,ε (y ), k = 0, . . , N1,ε } . N1,ε 0 Clearly dim(M1 ) = N1,ε + 1, and for any u = u 2 Sε = 1 ε N1,ε βk2 , (TSε u, u)HSε = 0 1 ε βk φk uk,ε there holds N1,ε µk,ε βk2 which implies 0 (TSε u, u)HSε 1−γ ≤ −ε 2 .

Since u3 is orthogonal to H2 , we get (u3 , v)HΣε = (u3 , A1 )HΣε + (u3 , A2 )HΣε + (u3 , A3 )HΣε + (u3 , A4 )HΣε + (u3 , A5 )HΣε .
