Abstract

Short geodesics are important in the study of the geometry and the spectra of Riemann surfaces. Bers' theorem gives a global bound on the length of the first 3g33g-3 geodesics. We use the construction of Brooks and Makover of random Riemann surfaces to investigate the distribution of short (<log(g)< \log (g)) geodesics on a random Riemann surfaces. We calculate the expected value of the shortest geodesic, and show that if one orders prime non-intersecting geodesics by length γ1γ2...γi,...\gamma_1\le \gamma_2\le ... \le \gamma_i ,..., then for fixed kk, if one allows the genus to go to infinity, the length of γk\gamma_{k} is independent of the genus.
