Orbit counting in conjugacy classes for free groups acting on trees
In this paper we study the action of the fundamental group of a finite metric
graph on its universal covering tree. We assume the graph is finite, connected
and the degree of each vertex is at least three. Further, we assume an
irrationality condition on the edge lengths. We obtain an asymptotic for the
number of elements in a fixed conjugacy class for which the associated
displacement of a given base vertex in the universal covering tree is at most
. Under a mild extra assumption we also obtain a polynomial error term.Comment: 13 pages, additional section discusses error terms, revised

On Vector Bundles of Finite Order
We study growth of holomorphic vector bundles E over smooth affine manifolds.
We define Finsler metrics of finite order on E by estimates on the holomorphic
bisectional curvature. These estimates are very similar to the ones used by
Griffiths and Cornalba to define Hermitian metrics of finite order. We then
generalize the Vanishing Theorem of Griffiths and Cornalba to the Finsler
context. We develop a value distribution theory for holomorphic maps from the
projectivization of E to projective space. We show that the projectivization of
E can be immersed into a projective space of sufficiently large dimension via a
map of finite order.Comment: version 2 has some typos corrected; to appear in Manuscripta
