WebDue to a planned power outage on Friday, 1/14, between 8am-1pm PST, some services may be impacted. Webthe author proved in [Ra1] a relation between the average indices of these closed geodesics. With the help of the normal form of a linear symplec-tic map which we discuss in section 3 we show in section 5 that for a strongly bumpy Riemannian metric the average indices depend linearly on the Poincar e exponents.

Webπ(λ +1), these geodesics only differ by orientation, cf. [Ra4, ch.5], [Zi, p.142]. Using the Morse inequalities, the topology of the space of unparametrized closed curves on S2 and a detailed analysis of the sequence ind(cm) of Morse indices of the m-fold covers cm of a closed geodesic c we obtain the following existence result WebClosed billiard trajectories in a polygon in the hyperbolic plane can be coded by the order in which they hit the sides of the polygon.

ON THE AVERAGE INDICES OF CLOSED GEODESICS
Webaverage indices provided the number of closed geodesics is finite. Key words: Finsler spheres, closed geodesics, index iteration, average index. AMS Subject … Webmany closed geodesics for any choice of a Riemannian metric. The celebrated the-orem of Gromoll and Meyer [GM69b, Theorem 4] motivated the formulation of the closed geodesics conjecture, by confirming its validity for the class of simply connected closed manifolds M whose free loop space has unbounded Betti numbers in some coefficient field F. Webclaim about the indices see the proof of Theorem (2.5) below. Our next aim is the construction of cycles in 77M mod 77°M which ... sectional curvature will be I < δ . We begin with some preliminaries. NON-HYPERBOLIC CLOSED GEODESICS 139 Choose a real number η in the open interval ((2σ — 2)π, π). This interval is non-empty since 2σ<3 ... immobilier boulay moselle
