✦ Synopsis

In this paper we study spectral asymptotics of degenerating families of hyperbolic Riemann surfaces, either compact or non-compact but always of finite volume. We prove that the second integral of the spectral counting function has an asymptotic expansion out to o(l), where l is the degeneration parameter. The first term in the expansion is a diverging term which depends solely on the degeneration parameter and the counting parameters and the second term is the second integral of the spectral counting function of the limit surface. 1997 Academic Press # # H(S) l (#) sinh(nl (#)Â2) e &(nl (#)) 2 Â4t , article no.

In this article we will study what we call weighted counting functions on hyperbolic Riemann surfaces of finite volume. If M is compact, then we define the weighted counting function for w 0 to be N M, w (T )= : where [\* n ] is the set of eigenvalues of the Laplacian which acts on the space of smo
