Perturbations of the Laplacian in Teichmüller Space

  • Peter Buser
Part of the Modern Birkhäuser Classics book series (MBC)


An important consequence of the real analytic structure of Teichmüller space is the analyticity of the Laplacian. In Buser-Courtois [1], for instance, this was used to show that the spectrum of a compact Riemann surface is determined by a finite part. That article also contains an outline proof of the analytic structure of the Laplacian. In this chapter we give a detailed account. The main theorems are contained in Sections 14.7 and 14.9. The finiteness result follows in Section 14.10. Sections 14.1 - 14.5 provide the necessary material from the perturbation theory of linear operators. These sections are based on Kato’s book [1] but are written in a self-contained style. Section 14.6 then links the general theory with Teichmüller space, where for convenience we recall the necessary facts from Chapter 6.
