This text is an introduction to the spectral theory of the Laplacian on compact or finite area hyperbolic surfaces. For some of these surfaces, called “arithmetic hyperbolic surfaces”, the eigenfunctions are of arithmetic nature, and one may use analytic tools as well as powerful methods in number theory to study them. After an introduction to the hyperbolic geometry of surfaces, with a special emphasis on those of arithmetic type, and then an introduction to spectral analytic methods on the Laplace operator on these surfaces, the author develops the analogy between geometry (closed geodesics) and arithmetic (prime numbers) in proving the Selberg trace formula. Along with important number theoretic applications, the author exhibits applications of these tools to the spectral statistics of the Laplacian and the quantum unique ergodicity property. The latter refers to the arithmetic quantum unique ergodicity theorem, recently proved by Elon Lindenstrauss. The fruit of several graduate level courses at Orsay and Jussieu, The Spectrum of Hyperbolic Surfaces allows the reader to review an array of classical results and then to be led towards very active areas in modern mathematics.

Dans ce mémoire, on décrit le début du spectre des longueurs de tous les groupes de triangles associés à un triangle hyperbolique (r,p,q) avec r,p,q entiers ordonnés dans l'ordre croissant. On montre alors que la donnée du spectre des longueurs caractérise, sauf si r=3 , la classe d'isométrie d'un tel groupe parmi tous les groupes de triangles

Most polynomial growth on every half-space Re (z) ::::: c. Moreover, Op(t) depends holomorphically on t for Re t> O. General references for much of the material on the derivation of spectral functions, asymptotic expansions and analytic properties of spectral functions are [A-P-S] and [Sh], especially Chapter 2. To study the spectral functions and their relation to the geometry and topology of X, one could, for example, take the natural associated parabolic problem as a starting point. That is, consider the 'heat equation': (%t + p) u(x, t) = 0 { u(x, O) = Uo(x), tP which is solved by means of the (heat) semi group V(t) = e- ; namely, u(·, t) = V(t)uoU· Assuming that V(t) is of trace class (which is guaranteed, for instance, if P has a positive principal symbol), it has a Schwartz kernel K E COO(X x X x Rt, E* ®E), locally given by 00 K(x, y; t) = L>-IAk(~k ® 'Pk)(X, y), k=O for a complete set of orthonormal eigensections 'Pk E COO(E). Taking the trace, we then obtain: 00 tA Op(t) = trace(V(t)) = 2::>- k. k=O Now, using, e. g., the Dunford calculus formula (where C is a suitable curve around a(P)) as a starting point and the standard for malism of pseudodifferential operators, one easily derives asymptotic expansions for the spectral functions, in this case for Op.

LE THEME CENTRAL DE CETTE THESE EST L'ETUDE DE CERTAINES PROPRIETES DE NEGATIVITE DE COURBURE DES SURFACES ALGEBRIQUES HYPERBOLIQUES AU SENS DE KOBAYASHI. L'ETUDE QUE NOUS AVONS FAITE EST DIVISEE EN DEUX PARTIES : DANS UN PREMIER TEMPS, NOUS INTRODUISONS LA NOTION DE CONNEXION PROJECTIVE PARTIELLE A COEFFICIENTS MEROMORPHES, ET MONTRONS COMMENT DE TELLES CONNEXIONS PEUVENT SERVIR A CONSTRUIRE DES OPERATEURS WRONSKIENS GLOBAUX AGISSANT SUR LES JETS DE COURBES HOLOMORPHES (UN TYPE TRES PARTICULIER DE JETS DE DIFFERENTIELLES INVARIANTES). GRACE A UN THEOREME D'ANNULATION DU WRONSKIEN REPOSANT SUR DES HYPOTHESES DE NEGATIVITE DE LA COURBURE DE RICCI ET GENERALISANT DES RESULTATS ANTERIEURS DE GREEN-GRIFFITHS, SIU ET NADEL, NOUS DONNONS DES EXEMPLES EXPLICITES DE FAMILLES ALGEBRIQUES DE SURFACES HYPERBOLIQUES DANS L'ESPACE PROJECTIF, DE DEGRE QUELCONQUE SUPERIEUR OU EGAL A ONZE. CECI ILLUSTRE UNE (TOUTE PETITE) PARTIE D'UNE CONJECTURE CELEBRE DE S. KOBAYASHI, QUI PREVOIT QU'UNE HYPERSURFACE GENERIQUE DE L'ESPACE PROJECTIF DE DEGRE ASSEZ GRAND (PAR RAPPORT A LA DIMENSION) EST HYPERBOLIQUE.

This book contains accounts of work presented during the research conference, ``Zeta Functions in Geometry,'' held at the Tokyo Institute of Technology in August 1990. The aim of the conference was to provide an opportunity for the discussion of recent results by geometers and number theorists on zeta functions in several different categories. The exchange of ideas produced new insights on various geometric zeta functions, as well as the classical zeta functions. The zeta functions covered here are the Selberg zeta functions, the Ihara zeta functions, spectral zeta functions, and those associated with prehomogeneous vector spaces. Accessible to graduate students with background in geometry and number theory, Zeta Functions in Geometry will prove useful for its presentation of new results and up-to-date surveys.

Geodesic and Horocyclic Trajectories presents an introduction to the topological dynamics of two classical flows associated with surfaces of curvature −1, namely the geodesic and horocycle flows. Written primarily with the idea of highlighting, in a relatively elementary framework, the existence of gateways between some mathematical fields, and the advantages of using them, historical aspects of this field are not addressed and most of the references are reserved until the end of each chapter in the Comments section. Topics within the text cover geometry, and examples, of Fuchsian groups; topological dynamics of the geodesic flow; Schottky groups; the Lorentzian point of view and Trajectories and Diophantine approximations.
